Why Microsoft 365

Microsoft 365 migration in Southern California — the productivity platform California businesses run on.

Microsoft 365 migration in Southern California is the foundational cloud move for most California businesses — Microsoft 365 covers email (Exchange Online), files (SharePoint and OneDrive), collaboration (Teams), and identity (Microsoft Entra ID) under one productivity suite. Most California mid-market businesses already use M365 in some capacity; the migration work is typically modernization, consolidation, security hardening, or platform switch from Google Workspace.

WCC's Microsoft 365 migration scope covers tenant setup, Exchange Online mail migration from on-premises Exchange or Google Workspace, SharePoint and OneDrive deployment with governance, Microsoft Teams rollout, identity configuration with MFA and conditional access via Microsoft Entra ID, Defender for Office 365 security setup, license optimization across Business Premium and E3/E5 tiers, end-user training, and operational handoff. Typical M365 migrations complete in 4-12 weeks.

Five Core Scopes

Microsoft 365 migration scope — five areas in every engagement.

M365 migration covers more than just moving mailboxes. Five core scope areas apply to every WCC M365 engagement, scaled to fit project size.

Mail & Exchange Online
Migration · Mail Flow · Hybrid

The most visible piece of the migration

Exchange Online migration covers mailbox migration from source (on-premises Exchange, Google Workspace, IMAP providers), mail flow design (connectors, transport rules, hybrid coexistence during cutover), distribution lists and shared mailboxes, mobile device configuration, calendar and contact migration. Cutover, staged, or hybrid migration approaches based on user count and downtime tolerance. Most migrations use coexistence for 2-4 weeks during transition.

Files: SharePoint & OneDrive
Governance · Sites · Sync

Where corporate data actually lives

SharePoint and OneDrive deployment covers site collection architecture (modern hub and spoke), permission strategy (groups not individuals), retention policies, classification and sensitivity labels, external sharing controls, OneDrive sync policies, file migration from on-premises file servers or Google Drive, and Power Platform governance. Governance done upfront is the difference between organized M365 and chaos.

Microsoft Teams
Collaboration · Voice · Governance

The collaboration platform replacing standalone tools

Teams deployment covers team and channel architecture, governance (team creation policies, naming standards, lifecycle management), external collaboration controls, meeting policies, Teams Apps governance, and integration with Office apps. Teams Phone optional — replaces traditional PBX with cloud telephony. Standard Teams licensing included in M365 Business Premium and E3; Teams Phone requires E5 or add-on license.

Identity: Microsoft Entra ID
MFA · Conditional Access · SSO

The control plane for everything M365

Microsoft Entra ID (formerly Azure AD) configuration includes MFA enforcement across all accounts, conditional access policies (geographic, device compliance, sign-in risk, named locations), single sign-on (SSO) for third-party SaaS apps, privileged identity management (PIM) for admin accounts, identity protection with risk-based sign-in, and hybrid identity for customers maintaining on-premises Active Directory. Identity is the most critical M365 security control.

Security: Defender for Office 365
Email · Endpoint · Cloud Apps

Beyond default settings that create real risk

M365 security configuration covers Defender for Office 365 (Safe Links, Safe Attachments, anti-phishing), Defender for Endpoint for managed devices, Defender for Cloud Apps (formerly MCAS), data loss prevention (DLP) policies, retention policies, eDiscovery for legal hold scenarios, sensitivity labels for data classification, and Secure Score baseline. Target Secure Score 75%+ for most California mid-market businesses, 85%+ for regulated industries.

Our Process

How WCC delivers Microsoft 365 migration across Southern California.

M365 migration runs in six phases — tenant setup before any user migration, pilot validation before bulk rollout, phased migration with end-user support throughout. Most California M365 migrations complete with zero unscheduled downtime.

01

Discovery & License Selection

Current state assessment — user count, mail volume, file storage, identity systems, compliance requirements. License recommendation across Business Premium, E3, and E5 based on actual feature needs. Most California businesses overspend on M365 licensing; right-sizing happens upfront.

02

Tenant Setup & Configuration

M365 tenant provisioning, domain verification, DNS configuration, baseline security setup (MFA, conditional access foundation), retention policy defaults, classification framework, and governance baselines. Tenant configuration before any user migration sets foundation for everything that follows.

03

Pilot Migration

10-15 representative users migrated as pilot — typically including IT staff and one business unit. Pilot validates migration approach, identifies edge cases, refines end-user documentation. Mail flow coexistence configured for hybrid period. Pilot runs alongside source platform for 1-2 weeks.

04

Bulk User Migration

Remaining users migrate in waves of 25-100 depending on total size. Each wave scheduled with end-user notification, executed in maintenance windows where possible. Files and SharePoint migration proceeds in parallel. End-user training delivered before each wave's cutover.

05

Security & Governance Hardening

Post-migration security work — Defender for Office 365 policy tuning, conditional access refinement, DLP policy implementation, sensitivity label rollout, Secure Score improvement work targeting 75%+. Governance policies enforced as user base stabilizes on M365.

06

Source Decommission & Handoff

Source platform decommissioned after migration validation — typically 30 days post-final migration. Documentation transferred to internal IT or WCC managed services. Operational handoff includes runbooks, admin training, and ongoing support model selection (internal, co-managed, fully managed).

FAQs

Microsoft 365 migration in Southern California — frequently asked questions.

Common questions about M365 migration — covering scope, cost, timeline, Google Workspace migration, license tiers, Teams Phone, security, and governance for Southern California businesses.

WCC's Microsoft 365 migration scope covers tenant setup and configuration, Exchange Online email migration (from Exchange on-premises, Google Workspace, or other providers), SharePoint Online and OneDrive deployment, Microsoft Teams rollout with governance, Microsoft Entra ID (Azure AD) identity configuration with MFA and conditional access, Defender for Office 365 security setup, license optimization (E3 vs E5 vs Business Premium), end-user training and adoption, and operational handoff. Typical M365 migrations complete in 4-12 weeks depending on user count and source platform.
Microsoft 365 migration cost depends on user count, source platform, and scope. Small business migration (under 25 users): typically $5,000-$15,000. Mid-market migration (50-200 users): typically $15,000-$60,000. Enterprise migration (500+ users): typically $50,000-$200,000+. Ongoing M365 licensing is separate — Business Premium $22 per user per month, E3 $36 per user per month, E5 $57 per user per month (current Microsoft pricing). WCC provides fixed-fee migration pricing after scoping and helps optimize license selection to avoid overspending on features you don't use.
Yes — Google Workspace to Microsoft 365 is one of the most common migration patterns for Southern California businesses. Migration scope includes mail migration (Gmail to Exchange Online), file migration (Google Drive to OneDrive and SharePoint), calendar and contact migration, identity migration (Google to Entra ID or hybrid), and user training to ease the platform transition. Coexistence is supported during cutover — mail flow routing between Google and Microsoft for the migration period, typically 2-6 weeks depending on user count. Most California businesses moving from Google Workspace are driven by cost, Microsoft ecosystem integration, or Teams adoption.
Three primary commercial tiers. Business Premium ($22/user/month): full Office apps, Exchange, SharePoint, OneDrive, Teams, plus Defender for Business and Intune. Capped at 300 users. Best for small businesses needing security baseline. E3 ($36/user/month): Business Premium plus enterprise mobility, advanced compliance features, unlimited user scale, more SharePoint and OneDrive storage. Best for mid-market and any business over 300 users. E5 ($57/user/month): E3 plus Defender for Office 365 P2, Microsoft Defender for Endpoint, Microsoft Sentinel integration, advanced compliance (DLP, eDiscovery, retention), Power BI Pro, and Teams Phone. Best for regulated industries, security-conscious enterprises, or businesses adopting Teams Phone. WCC scopes license tier against actual feature requirements.
Yes. Microsoft Teams Phone replaces traditional PBX phone systems with cloud-delivered telephony through Microsoft Teams. WCC's Teams Phone scope includes phone number porting from existing carriers, calling plan selection (Microsoft Calling Plans, Direct Routing via SIP, or Operator Connect), auto attendant and call queue configuration, contact center integration if applicable, handset selection (Yealink, Poly), and end-user training. Teams Phone typically lands $8-$15 per user per month including calling plans, significantly less than legacy PBX licensing plus carrier costs. Strong fit for businesses already standardized on M365.
Microsoft 365 migration timeline depends on user count, source platform, and data volume. Small business (under 25 users): typically 3-6 weeks. Mid-market (50-200 users): typically 6-12 weeks. Enterprise (500+ users): 3-6 months with phased rollout. WCC's typical approach: tenant setup and configuration (week 1), pilot with 10-15 users (weeks 2-4), bulk migration in waves (weeks 4-10), security and governance hardening (weeks 8-12), end-user training and adoption support throughout. Source platform decommissioning happens after validation.
M365 security is critical — most California businesses with M365 leave significant default settings that create real risk. WCC's M365 security scope includes Microsoft Entra ID configuration (MFA enforcement, conditional access policies, named locations, risk-based sign-in), Defender for Office 365 setup (Safe Links, Safe Attachments, anti-phishing), Defender for Endpoint for managed devices, Microsoft Defender for Cloud Apps (formerly MCAS), data loss prevention (DLP) policies, retention policies, eDiscovery for legal hold scenarios, and Secure Score baseline targeting 75%+ for most California mid-market businesses.
License optimization is a distinct practice within M365 engagements. Most California businesses overspend on Microsoft 365 by 15-30% — over-licensed users (E5 for everyone when E3 would suffice), unused add-on licenses, stale accounts still consuming licenses, premium SKUs assigned to users who don't need the features. WCC's M365 license optimization reviews actual feature usage per user, recommends right-tier licenses per role, identifies stale accounts for cleanup, and consolidates add-on licenses where possible. Typical engagement delivers 15-25% license cost reduction with no feature loss.
Yes. SharePoint and OneDrive governance is the difference between a well-organized M365 environment and chaos. WCC's governance scope includes site collection design (modern hub and spoke architecture), permission strategy (groups not individuals, least privilege principle), retention policies, classification and sensitivity labels, external sharing controls, OneDrive sync policies, version history and recovery, and Power Platform governance for citizen developers. Particularly important for regulated industries where data handling controls are required for HIPAA, SOC 2, or other compliance frameworks.
