First of all thank you very much for your responses.
We have the following infrastructure:
Mail1 = the initial mail server with Domino 6.5 used to create the Lotus domain
Mail2 = a Backup aditional server replicating from mail1 to use in emergency
MailBranch = production mail server for supporting users in a branch in the same Lotus domain.
All above servers are in Domino 6.5 and Windows 2003 R2
What i did, was to shutdown and disconnect Mail2, install Centos 6 x64 and Domino 9 on a new machine but with exactly the same ip address and hostname with Mail2.
After this, i setup the Domino server as an aditional server pointing to the already existed Mail2.id which i took from the old Mail2.
The server is up and running and we can connect with Domino administrator succesfully, but no databases (mail files, SAV, names.nsf) yet replicated to it.
The mail files are 150gb and i do not want to push them via replication because we may face network performance issues.
Now i will try to copy names.nsf from the old Mail2 to the new one, which i think it will work and regarding the mail files, i think that i must copy them from a usb drive to the server and they will be recognized.
Is this approach correct?
Do you have to suggest something different or something to pay attention to?
Thank you very much
