“Until you have successfully migrated something
at least once, there is a high risk that there will
be an issue during / after the migration!”

Lessons Learned – Migration Process - #2
Test
Migrations
Perform at least 2 rounds of migrations before you do
the final production migration
 Helps to determine issues and expected duration for
complete migration
Don’t take
shortcuts
Shortcuts are the path to troublesome migrations.
Shortcuts lead to risks.
Risks lead to issues.
Issues lead to delays.

17. aOS Kuala Lumpur 2018aOS Kuala Lumpur 2018
Lessons Learned – Migration Process - #3
• Expect Throttling
• Reduce risk by
• Using dedicated migration
machines
• Using dedicated migration
accounts
• If possible, separate network
connections
 Azure VMs!

Final Migration & Go Live
Test Migrations should have provided the following
• List of issues and fixes  ideally fairly little time needed to execute
• Expected duration of the final migration
Step-by-step plan should be available and
migration should be straightforward
