Moving a Primary Domain

[BarryM45]

Hi
I wonder if anyone could help me clarify the following.
I have been asked to move a Groupwise 5.5 primary domain database to a new server in a site that has a configuration i have not seen before.

This site has 5 remote sites and one main head office. The head office has one Netware 5.1 that contains the post office and domains as well as the MTA's this server is getting old. The way this server has been configured is as follows:

Primary
-------MTA
-------APIGATE
Secondary
--------MTA
--------PO
----------POA

The other sites are configured as secondarys exactly as the secondary listed above. I have read the TID 1008433 and indeed i have moved a fair few domains in the past. However, i am not sure or at least a i am a bit lost on the grafting process for the primary. Normally i would graft the secondary PO and its users back on to the newly moved domain. As i am dealing with a primary without a configured PO do i still have to graft? As it is in this case with the primary should i graft all PO's in the tree back to the primary after the Database move? This is being done to accomodate a 6.5 upgrade.

It is worth pointing out that i have not moved a primary domain before.

Many Thanks
Barry
