Dear
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?
Dear AshokM
I had some successful experience in other organization with same Win2016+Exchange2016. Step is simple, 1.install .Net Framework 4.8. 2.Stop all exchange service. 3. Run as administrator to start CU20 SETUP.EXE.
So I think my step is correct.
I had not put server in maintenance mode before upgrading as other successful cases.
https://localhost/ecp not help me skip problem.
Yes, login page show properly. After input password and click login, below page show.
I need time to read your link, will reply if have news.
Thank you.
Best Regards.

Dear AshokM
I had read support Matrix link
I am running at win2008 R2 forest level with win2012R2 OS, .Net Framework 4.8 installed.

Hi,
Can you check the IIS bindings on Default web site and Exchange web site and make sure to have the proper certificates binded.
also, you could try UpdateCAS.ps1 and UpdateConfigFiles.ps1 scripts one after another and check if you are able to access OWa/ECP.
Dear AshokM
I checked, I think binding is correct.
where I can get 2 scripts?
Thank you.
Best Regards.

Hi,
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: https://theitbros.com/recreate-owa-ecp-virtual-directories-exchange-server-2016/

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

Dear EricYin
Nice to see you again.
Please focus at ECP issue as I had restore snapshot. Please forget CU20 at this moment.
I will try your link and reply.
Yes, I have DAG.
Best Regards.
Scott Gao
Dear Eric
recreate owa and ecp virtualdirectory not help my case. recreate owa and ecp WebApplication also not help.
I found all my database had not mount and I can not mount.
Thankyou.
Hi,
Since another server is dead and never recover, why do you still keep the DAG?
Try restarting the“Microsoft Exchange Replication” Service, if still can't mount it, I‘d like to see the specific error info of test-replicationhealth:
Test-Replicationhealth -identity server|fl check ,error
Dear Eric
To easy mask, I update by TXT.
I can remove dag if needed, would you please advise how?
I had reboot whole server or replication service, no help.
sorry for basic question. The database listed in "get-mailboxdatabase" is protect in DAG or not? If not, how can I know what is protect in DAG?
Thank you.
Scott Gao.
