Best Time to Schedule Cutover for Slack to Teams Transitions

When planning a Slack to Teams transition, planning for cutover and its timing is very important. Similar to creating an action plan for all stages of the migration, your IT team must plan around the cutover phase to ensure users onboard Teams without any disruption.

In this brief article, we have shared actionable insights on planning for cutovers.

Key Takeaways:

  • A cutover is the final step of transitioning from the source to the destination cloud.
  • Off-peak hours and weekends are the best time to schedule the final cutover.
  • Post-final delta migration is the best stage to schedule the final cutover.

What Exactly is a Cutover and Why is it Important?

A cutover is a collection of steps to perform at the end stages of any cloud migration project, including Slack to Teams migration. One of the main steps of a cutover is performing the final delta migration to sync the final incremental changes users make. In full tenant migrations, cutover tasks also include DNS/routing changes.

The criticality of a cutover is that after it is completed, businesses permanently transition from the source to the destination cloud. And in most cases, the source cloud is decommissioned.

What is the Best Time to Schedule Final Cutover for Slack to Teams Migration?

The best time to schedule a final cutover for Slack to Teams chat migration is during off-peak hours. Weekends present the best time window as all employees are on leave, and there are no user activities in the source and destination cloud.

So, the question you might ask is why not schedule the final cutover during weekdays when users are working?

The main reason is that when users are working during cutover, more new changes get accumulated in Slack channels and DMs, which, in turn, makes the final delta migration irrelevant.

And to migrate those new incremental changes, a new delta migration and cutover is required. So, the loop keeps repeating.

Tip: We strongly recommend scheduling the final cutover during weekends as this strategy has worked for all our customers.

At What Stage Should You Schedule Final Cutover for Slack to Teams Migration?

You must schedule the final cutover after performing the final delta migration. This helps you ensure that there are no important leftover data, such as chat messages, attachments, etc., when performing the cutover to ensure a complete Slack to Microsoft Teams transition.
