I would upgrade then replicate or move user to the new server… But then that is me talking…
Couple of things I might discuss…
1- Why not go to 8.5.1 and avoid the bugs of 8.5?
2- If moving to or upgrading on Linux, you may want to delete all the FT files before you restart the server… I just did one and it gave me quite a bit of hell…
3- Domino with user files on DMZ? While this works, it is not someting I would consider… Not before considering any VPN solution or even consier Lotus Mobile Connect.
Finnally i installed the domino R851 on linux as secondary server in our R5 Domain.It seems work fine, i can start it up in this way:
logon as root
open a shell and do “su domino85” (domino85 is my linux user)
cd /usr/local/notesdata
/opt/ibm/lotus/bin/server
Then in the shell i can see the domino console.
I’m tryng to daemonize the server using the script in /etc/inid.d/domino it looks like domino is started but it doesn’t work, probably because the server.id require a password?
The last question… how could i move the mail databases from R5-win to R851-linux?
I like upgrading in place no matter how many servers. I know, some people will not recommend it but the reason I like it is that you separate the issues… 1 you upgrade and 2, you move. The other way, you have to do both at the same time…
In my book, who cares how many servers you have for a short period of time… At least, you do not have to worry about 2 things at the same time.
I would not replicate manually. Like I said before, there is a function in Domino to move users and get everything modified at the same time (including location documents on the users). It is very painless and will save you lots of aggravation. Test it on yourself. Right Click your user doc in the address book and select “Move to Another server”… Adminp will take care of the rest.
I am still puzzled as to why you want to put a server with mailfiles in the DMZ. This is something I would not consider doing. You really should consider Lotus Mobile Connect. It is very secure and easy to configure and manage.
