DBCOPY still the way to go, when move groupwise to another server?

We want to move our GW14.2.x mailsystem to a new SLES12 GM18.2.x mailsystem. Are this  DBCOPY command still the best way to get all the mail data over to the new servers ?

For Postoffice:

dbopy -m -p -f -k <source> <destination> for the first copy, and

dbcopy -m -s -f -k <source> <destination> for the second, and last copy.

Same for the domain data, using the -d (=domain).

And last dbcopy before running on the new server, the poa agents on the source server needs to be stop running.

Or are the better way, to move to GW18.2.x without losing data ?

Kind regards, Henk

Dbcopy is the official recommendation.

I prefer rsync because it is faster and offers more possibility.

I prepare my environment in this way:I run a rsync job every day. The first one needs a lot of time. Usually I do it with these options: rsync -avz --delete source-directory server:target-directory (if you want to run this without passwords then you have to prepare a password-less login method for ssh. There are a lot of articles out in internet for ssh-keygen and more). I use --delete to delete files at the target location if they have been deleted at source.

On the final day I stop my groupwise at the source server and run a final rsync. Immediately afterwards I rename my source-directory for GroupWise to avoid problems in case if you restart i.e. this old server.

Hello Diethmar, thank you for your response. Can rsync also be used on live groupwise systems? Because the mailbox from each user is a database, we where thinking on DBCopy.
But rsync can also get along with open databases ?
And are you running rsync from the source server, or from the destination server? Kind regards, Henk

Since Diethmar hasn't replied yet, I'll jump in here.  Yes, you can run rsync against the live post office.  That's why he mentioned running it multiple times.  You run it a few times while live to get most of the information over and then you shut down GroupWise for a final run to make sure everything is perfectly in sync.  This minimizes down time for the post office.  When I do it, I run rsync at the source GW server.

Thank you Ken.

Sorry, I did not seen your question @hko .

I agree to Ken. Yes, I use it for my live postoffice.
