Install Migration Assistant Failed.

[as900w]

I have a vCenter for Windows.

I want to migration it  to VCSA.

But, I install Migration Assistant failed.

"Unable to connect to VMware Update Manager Database, Cannot proceed with migration."

I view vSphere web Client, The database is OK.

I can upgrade ESXi using VUM.

Hi,

did You run it on VUM machine?

[as900w]

VUM and vCenter Server on the same server.

Check if You are using appropriate Windows/domain user account when You are running Migration Assistant.

What permissions does the user need to run？

I running it using domain administrator.

Make sure the account you use has access to the VUM database.

[as900w]

Running account of Migration Assistant own SQL Full Permission.

And it is domian administrator

"If your vCenter Server service is running in a service user account for access to the vCenter Server database and you run Migration Assistant under a different account, the Migration Assistant account must have the Replace a process level token permission."

Do you honestly need to migrate VUM? In the vast majority of cases I see, you don't. If this is the case, simply uninstall VUM and the migration assistant won't look for it. Once your upgraded vCSA comes up, a brand new VUM will be baked into it. Makes life a lot easier.
