I have a client currently running a single Win 2003 Server (2.6ghz, 1gb, 160gb), on this they have all files / folders, a workgroup email system called Tobit (which I hate) and Sage Line 100 (when I say this is running on the server what I mean is the Sage folder is shared on the network and is run locally on each machine (its a DOS app).
Software RAID 1 on 2 IDE disks
This is running with a Servgate SG100 Firewall and ADSL modem for internet / VPN connectivity.
This network was also setup with a very common 192.168.1.* IP scheme (not my doing).
Currently running about 40ish users.
I have got the go ahead to install a Small Business Server 2003, a new server to run it, a much better Firewall / UTM Device (Servgate Edgeforce M30), new switches etc etc.
My plan is to have the new server running SBS 2003 (and so managing all file / print / email tasks) and rebuild the current server using new hard disks (software raid 1 as current) to run the Sage line 100 app (or basicaly share the folder) (far easier than messing around with the current install and a cleaner end result, also able to keep the old disks as back up if everything goes wrong).
I also want to change the IP scheme to something a bit more obscure so users will be able to VPN in easily without having to change router settings at the remote end.
Now I need some advice...
I'm trying to figure out the best way to migrate to the new setup, minamising downtime.
The users obviously don't want any down time, all sales / production / delivery is based around the Sage line 100 system so this must suffer as little downtime as possible.
I have no hope of exporting any data from the Tobit system so I am just leaving that and asking users to backup any important emails manualy (save as HTML).. hopefully this should not cause to many problems.
I'm willing to work the weekends but just the simple number of pcs means I will not be able to setup all of them before the next day starts!! (they start at 5am) lol
Sage downtime is my main concern.
Advice please... Basicaly I'm looking for help with my implimentation plan.
