How-to move ISA server 2004 to a new server
Posted on 2006-03-29
We've been having hardware difficulties with our existing ISA 2004 server. It's installed on Windows 2003 server. The decision has been made to purchase a new HP branded Windows 2003 server with ISA pre-installed. We want to move the existing server / ISA config to the new hardware as seamlessly as possible. We've got the new hardware in hand, but are a little short on documentation as to how to perform this procedure. Since the current ISA server handles all Internet traffic for 14 office locations and VPNs from several offices, we'd like to pre-configure the new server off-line as much as possible before we attempt the actual install. Naturally, we want to configure the new server with the same IP config, same server name, same routing info, etc. What little procedure we've been able to develop so far is as follows:
ISA server move:
- extract all config info from current server ( OS, routing, VPN, ISA, surfcontrol, etc. ). Disk cfg is c:=10GB, D:=26GB, mirrored.
- gather all required software CDs, license info
- setup new server off-line - Apply SPs to OS, install required services ( i.e. Term serv, etc )
- Harden server 2003 OS.
- apply patches, set interfaces to internal / external with exact IP addresses from previous ISA server. Physically identify which interface is int / ext for connection purposes.
- install Surf-control
Saturday – live migration:
- remove current server from Domain, remove server/computer object, disconnect from network
- Force AD policy sync ???
- Move Digi board to new server. Install drvrs.
- Connect new server to network, add to domain with same computer name, IP config, routing
- setup RRAS from prev config info.
- Setup TS from prev cfg info.
- load exported config file backup for ISA, surfcontrol
- set auto updates to dload, but not auto install.
Naturally, these are the broad strokes. We need some help with the sequence of tasks as well as task details. If anyone can help us fill in the blanks or refer us to detailed docuemntation for this procedure, it would be most appreciated.
