Migration Exchange 2010 to 2016 Databases are not showing in ECP

I am migrating from Exchange 2010 to Exchange 2016. The issue I am facing that after installing Exchange 2016 the databases of Exchange 2010 and the default database of Exchange 2016 are not showing in ECP. When I try to create a new database having the error message

"Failed to mount database. Error: An Active Manager operation failed. Error: Couldn't find the specified mailbox database with GUID.

Please restart the Microsoft Exchange Information Store service on the server after adding new mailbox databases."

After restarting the service database folder creates in the drive location but the database is not showing in Database ECP.

Can anyone face this before and what is the root cause of this issue?

Please assist.

Hi @InnocentHeartvoice-2401

Did you mean you cannot see any databases (the existing ones and the newly created ones) in the Exchange 2016 ECP?

Please run this command via Exchange Management Shell(EMS) on Exchange 2016 and see if it returns all the databases:

 Get-MailboxDatabase -Status -IncludePreExchange2013 | fl name,mounted*

And if you run the following command via EMS to mount the newly created database, will there be any error message?

 Mount-Database -Identity Ex16\NewDB
