UVMS and DUAS nodes will be built on a fresh new servers, so we'll reinstall everything.
We'll first move&re-install two UVMS servers (primary&secondary failover).
My initial plan has been that we'll install UVMS to the two new servers in the new network. UVMS servers will be added to the same company with new hostnames etc.
So for a moment we would have total of 4 UVMS servers available.
And after the new servers have been working ok, we'll uninstall the old UVMS servers totally.
We will use the same external DB also.
In the manual and UVMS installer there are terms "primary" and "secondary" but I haven't found anything about these in the settings.
And according to UVMS manual we can install it to several servers:
Several UVMSs, installed on different physical or virtual machines, can coexist on the same database. The machines must use the same Time Zone, and the time must be synchronized internally.
I don't want to create any new databases or Company names in DU if there is no need to.
The connection from new network to old network will work, so we are not doing this in a "big bang". We'll move DUAS servers as we can move them.
