I had read many similar question and Google.
I install cu20 on exchange 2016 cu7. But fail at Step 14 of 18: Mailbox role: Mailbox service. main error message as below.

 " was run: "System.InvalidOperationException: Failed to mount database "FFFFF Database". Error: An Active Manager operation failed. Error: The database action failed. Error: Database 'FFFFF Database' on server 'FFFF-EX01' cannot be mounted due to a previous error: At '11/29/2020 12:46:25 AM' the Exchange store database 'FFFFF Database' copy on this server appears to be inconsistent with the active database copy or is corrupted. For more details about the failure, consult the Event log on the server for other storage and "ExchangeStoreDb" events. A successful failover restored service.  

I restore snapshot that before install, but problem had not gone. When I login ECP, after first login page, server return "HTTP error 500" with link https://domain/owa/auth.owa
I found all service component inactive. I reference below link to reactive but nothing change.
Would you please help if you have idea?
Thanks for your valuable time.

Best Regards.

    Hi @Scott Gao ,

    Please note that upgrading Exchange 2016 CU7 to CU20 is a big step. Could you provide more information to identify the cause.

    Have you installed and verified the pre-requisites for CU20 as the .NET framework version requirements are different for both CU's.
    Did you put the servers in maintenance mode before upgrading?
    Are you able to login using https://localhost/ecp on the server?
    Are you getting the login page? HTTP 500 occurs before or after entering the credentials?

    Please let me know, do you want to solve the ECP issue or migration issue in this thread? So that we could focus on one of it.

    Can you open OWA now? We could try recreating ECP/OWA virtual directory:

    Do you have a DAG? Test-Replicationhealth is normally used to check replication or Active Manager health in a DAG.
