I want to move my existing OmniBack II 3.5 server to new Hardware (WINtel). What files do I have to copy to the new box to keep my config and databases?

3. re-install Omniback on the new box (mostly so the registry stuff gets re-created)
Similarly on HPUX to HPUX it is a file copy and re-install - altho there are three paths...
/etc/opt/omni
/var/opt/omni
/opt/omni
You can also do an Omnidbutil -writeascii out from one box, install omniback on the gaining box, then do an omnidbutil -readascii into the gaining box...
You could do an Omniback database backup on the losing box, install Omniback on the gaining box, and set up a tape drive, then restore the database from your backup to a temp location, stop Omniback, then move the good data into place.
Crossing platforms is 'wobbly' I have seen scenarios and documents that implied it could be done. I have also seen documents that said 'not supported.' I KNOW that there are significant differences I the underlying engines - and I am sure it is a bad idea.
Finally - this would be supported... install a new installation, then IMPORT any tapes you cared about...which takes as much as 4 hours per FULL DLT tape.
We are also just beginning the process to move our cell manager to an intel box.
What the HP guy has said is correct. You must export the database into an ascii text file, and then convert it into a unicode file on the intel box, and then import it again. There is a utility provided to convert the database from ascii to unicode.
The database will take a long time to export and import. Depending on the size, expect to be waiting a number of hours.
Check out the documentation on the omniback part of the HP site, or contact me if you need any more info.
As I said, we are currently in the planning stages of this migration.
we are also in process of moving the OB 3.5 Cell Manager from an NT Server to an W2K Server.
I want to try the copy files/new installation way but need some clarity on the procedure.
1. copy the current contents of the \program files\omniback server to a backup folder on the old server
2. install OB on the new server
The question now is what files do I have to copy from the old system.
I guess one has to copy the db folder and subfolders from the old system and the \config\cell folder.
Is that correct? Does anyone know if there are other important files that need to be copied?
The following two directories must be copied when switching from one Windows CM to another:
1) \program files\omniback\db - here is the database
2) \program files\omniback\config - here you have all the configuration
When copying these two directories make sure that the OmniBack II processes are down.
If your new Cell Manager will have a new hostname, you must also run the omnidbutil -change_cell_name command from the Omniback\bin. This also means that you will have to update the cell_server file and the HKEY_LOCAL_MACHINE\SOFTWARE...\OmniBackII\Site\CellServer registry entry on all the clients. Maybe the easier way is to keep the same hostname on the new Windows CM.
