BE 3600 Upgrading: CASO first? or MMS?

First you need upgrade CASO and then MMS.

Refer to the below forum thread.

Thanks for your reply, AmolB.

1) Also, to play safe, do I need to backup anything first, e.g. the whole Catalog directory, any job settings, etc.?

2) After the upgrade, do I need to perform on the appliance, i.e. Dedeplication disk,  the action "Inventory and Cataloging"?

You should always grab manual copies of the Data & Catalogs folders before doing any major upgrades. These 2 folders will allow you to recover Backup Exec if needed.

Thanks!

I know the catalogs folder resides in D:\BackupExec\Catalogs. But where is the Data folder that you are referring to?

%InstallationDirectory\Data

Thanks!

I got 2 folders named Data, which one is the correct one?

1) D:\Application_Dedup\data <---actually my partition D's label is "Data" too

2) C:\Program Files\Symantec\Backup Exec\Data

Thanks.
