Best Practice for Copying Static Journal Databases

I have a DAG with 2 member servers (PRIM-EXCH and ALT-EXCH). PRIM-EXCH is the primary server. ‎ALT-EXCH is a standby server (which will be activated in the event PRIM-EXCH goes down.) I have 7 ‎static journal databases I need to copy over to ALT-EXCH. I am not using AutoReseed. So when I use ‎EAC to create a copy of a journal database, database is copied over successfully but I get the error ‎message: The seeding operation failed. Error: An error occurred while running prerequisite checks. ‎Error: The specified database isn't configured for replication and therefore cannot be used to ‎perform seed operations.‎
Microsoft articles I’ve come across for the error suggest its an error I can ignore but that I need to ‎use Update-MailboxDatabaseCopy cmdlet to seed the newly copied database. ‎

Is it better to take the time and setup AutoReseed? Or is seeding a database manually (via update-‎MailboxDatabaseCopy) just as good? The journal databases get pretty big…500GB to 750GB.‎
Please be aware, once the static Journal databases are copied over, they will be dismounted. (They are ‎only mounted when staff needs to search for emails (i.e. audits, compliancy checks).‎
I also will need to make a copy of the live User Mailbox Database and current active journal. ‎
Please advise.‎
Thank you,‎

Hey there. Thats an all too common issue when doing the initial replication.
Use the Update-MailboxDatabaseCopy command to kick it off again and it will be successful after that in most cases.
If the replication is not already suspended for that database to that server, it will throw an error telling you to do that first (Suspend-MailboxDatabaseCopy)
So suspend that copy first, then run Update-MailboxDatabaseCopy and you will be good to go.

AutoReseed is really designed for disk failure, so it doesnt apply here :)

Hi Andy
Sorry it took a bit to update you.

All is well. the Update-MailboxDatabaseCopy is working fine (I have 4 large Journal databases copied....3 more to go!)

Thank you again for all your help!

Got it...!

Thank you Andy! That's what I thought after reading about AutoReseed. That it may be a feature I don't particularly need right now.
I am set to do the Update-MailboxDatabaseCopy tomorrow and will let you know how it goes.
Thank you again for your help and support. Your answers are always so spot on!

Thank you,
