Microsoft 365 Migration
Email, files and data from Google Workspace, GoDaddy, on-prem Exchange or other tenants, with zero data loss.

Microsoft 365 · Toronto & GTA
Certified Microsoft 365 experts helping GTA businesses migrate, secure, and get more out of Microsoft 365 — fully managed, so your team can focus on work.
Whether you are moving off an ageing Exchange server, cleaning up a tenancy nobody owns, or working out which licences you actually need, our team delivers Microsoft 365 support Toronto businesses can rely on: migration, security, Intune device management and day-to-day management from one local provider.
The problem we solve
Most GTA businesses bought Microsoft 365 licences and stopped there. Nobody sized the plans, enforced multi-factor authentication or cleaned up sharing, so the tenant quietly becomes a security risk and an ongoing overspend at the same time. These are the four patterns we find in almost every environment we assess.
Staff on premium plans for work they never do, leavers still licensed, and duplicate add-ons billed monthly with no owner.
No MFA, no Conditional Access and default email filtering, leaving the tenancy open to the account takeovers behind most ransomware.
Data scattered across email attachments, local drives and personal OneDrive accounts, with no version control and no way to find anything.
Microsoft 365 was set up once by whoever had time, then never reviewed as staff, devices and clients changed around it.
Sun IT Solutions sets it up right and manages it for you.
What we do
One team covers the tenancy end to end, so licensing, security and support do not sit with three different suppliers.
Email, files and data from Google Workspace, GoDaddy, on-prem Exchange or other tenants, with zero data loss.
Right-size Business Basic, Standard, Premium and E3/E5 licences so you stop paying for capability you do not use.
MFA, Conditional Access, Microsoft Defender and Entra ID configured properly, then monitored continuously.
Enrol, secure and manage laptops and phones remotely, including compliance policies and remote wipe.
Structured file storage, permissions and collaboration setup that staff can actually navigate.
Microsoft Purview, data loss prevention, retention policies and email archiving for the records you must keep.
Third-party backup for Exchange, OneDrive, SharePoint and Teams, with long retention and single-item restore.
Prepare your data, permissions and team to safely adopt Copilot, with governance in place before rollout.
Migration process
Migration projects fail on planning, not on technology. Every move we run follows the same five stages, with sign-off between each one.
Step 1
Review your current environment, users and data, including what nobody remembers is still in use.
Step 2
A migration roadmap, licensing recommendation and cutover schedule agreed in writing.
Step 3
Email, files and calendars moved after hours in staged batches to avoid disruption.
Step 4
Security baselines, MFA and policies applied before users are handed the new environment.
Step 5
User onboarding, quick reference guides and ongoing managed support from the same team.
Security & compliance
Default settings are not a security strategy. We configure Microsoft 365 security so that identity, email and data controls work together, and so your team can evidence them when a client or insurer asks.
Microsoft 365 data hosted in Canadian datacentres, with the tenant location confirmed and documented.
Policies that check device health, location and sign-in risk before a session reaches your data.
Defender policies blocking phishing, malicious attachments and the invoice fraud attempts aimed at small business.
Microsoft Purview identifies sensitive information and stops it leaving the organization by email or share link.
Ongoing review of alerts, sign-in anomalies and Microsoft Secure Score, with the gaps closed in priority order.

Copilot readiness
Copilot can access everything the signed-in user can access, which means years of loose SharePoint permissions and duplicated files become visible all at once. Permissions and data governance have to be cleaned up before rollout, or Copilot confidently surfaces the wrong document to the wrong person.
Ask About Copilot ReadinessFind overshared sites, stale access and broken inheritance before Copilot indexes it all.
Sensitivity labels, retention rules and a tidy SharePoint structure Copilot can work from.
Practical guidance on prompting, verifying answers and knowing what not to paste into Copilot.
Plans
Microsoft 365 for small business usually needs a mix of plans rather than one. These are the three we recommend most often.
Web and mobile apps, email, Teams and cloud storage.
Best for frontline, shift and email-only users.
Adds the full desktop Office apps staff expect.
Best for most office staff.
Adds Intune device management, Defender and advanced security.
Best for businesses that need strong security and compliance.

A typical 20 to 50 user migration from Google Workspace, GoDaddy or an on-premise Exchange server takes two to four weeks from kickoff to cutover. Email and file moves usually run overnight across a weekend, and larger or multi-site environments can take six to eight weeks. Data volume and how much cleanup the source environment needs set the schedule.
No. We copy mailboxes, calendars, contacts, SharePoint and OneDrive data in stages and verify item counts before cutover. The source environment stays intact and read-only until you sign off, so anything missed can still be retrieved afterwards.
Yes, and it is one of our most common projects. Gmail, Calendar, Drive, shared drives and contacts map cleanly to Exchange Online, OneDrive and SharePoint. We run coexistence during the transition so mail keeps flowing both ways until everyone has moved.
Microsoft 365 can keep your Exchange, SharePoint, OneDrive and Teams data in Canadian datacentres when the tenant is provisioned with Canada as its data residency location. We confirm and set that during deployment, then document where your data lives so you can answer client and privacy questions.
Microsoft protects the service, but its built-in retention windows are short and do not cover accidental deletion, ransomware encryption or malicious insider activity the way a dedicated backup does. We add third-party backup for Exchange, OneDrive, SharePoint and Teams, with long retention and fast single-item restore.
It depends on how your staff work rather than how many of them there are. Email-only and frontline users suit Business Basic, most office staff need Business Standard for the desktop apps, and businesses with compliance or device management requirements should be on Business Premium. We review your users and recommend the most cost-effective mix.
Yes. We take over the tenant, audit what is assigned against what is actually used, and clean up duplicate, inactive or wrong-tier licences, including moving some users between plans. Microsoft 365 managed services from us cover licensing, users, security and support in one monthly plan.
Copilot reaches everything the signed-in user can reach, so oversharing has to be fixed first. That means reviewing SharePoint and OneDrive permissions, applying sensitivity labels, clearing out stale content and training staff on what Copilot will surface. We assess readiness, then run a controlled pilot with a small group before wider rollout.
