Moving to new server hardware: How to deal with PDC transition Old > New?

Hi,

I have been running my 6.x COS server for years without ANY hiccups whatsoever and the only downside I can see in that is that I had to tend to is so absolutely darn little that my Linux skills and ~knowledge have faded away badly. - Therefore it took me a bit to overcome my embarassment and to even ask this question, but here goes...

COS 7.3 has just been released and it is high time to move my server to a higher spec'd hardware base. However, during or after the install the new server would have to assume its role as the new PDC and the old server would ultimately have to be removed from its role, probably/hopefully with a synchronization step in between.

My question now is how to best go about this, i.e. what steps to take in what sequence? Is there perhaps some precanned information you can point me to or did I perhaps miss some relevant forum posts?

TIA,
Ingmar
