be at least twice the size of the Microsoft SQL Server core table returned in Step 2.
b The size of the statistics, events, alarms, and tasks (/storage/seat) partition of the embedded
PostgreSQL database must be at least twice the sum of the sizes of the Microsoft SQL Server
events and tasks and statistics tables returned in Step 3 and Step 4.
For example, if the Microsoft SQL Server core table is 100 MB, the events and tasks table is 1,000
MB, and the statistics table is 2,000 MB, then the Postgres /storage/db partition must be at least
200 MB and the /storage/seat partition must be at least 6,000 MB.
Download and Run VMware Migration Assistant on the Source
Windows Machine
You must download and run the VMware Migration Assistant on your source vCenter Server,
vCenter Single Sign-On, or Platform Services Controller to prepare it for migration from Windows to an
appliance. If you are using a deployment of vCenter Server with an external Update Manager that runs on
Windows, download and run the VMware Migration Assistant on the source Windows machine where
Update Manager runs to prepare Update Manager server and database for migration from Windows to
the vCenter Server Appliance.
The VMware Migration Assistant performs the following tasks on the source Windows machine where you
run it:
1 Discovers the source deployment type.
2 Runs pre-checks on the source.
3 Reports errors that must be addressed before starting the migration.
4 Provides information for the next steps in the migration process.
Ensure that the VMware Migration Assistant window remains open during the migration process. Closing
the VMware Migration Assistant causes the migration process to stop.
Prerequisites
