Span IP Range across two sites via Cisco ASA Site-to-Site VPN
HI EE,
For one site I have a mixture of 75 servers and 325 end-user devices. This IP range has approximately 400 IPs in use. I need to move my servers to a new location and thus put them in theory on a new IP range. My time is very limited and I can't change all the IPs on the end user devices. Our notes are also very limited and I can't successfully change all of the server IPs with limited downtime.
Details:
IP Range: 10.35.208.0/20
75 servers
325 end user devices
New site will be via a Cisco ASA Site-to-Site VPN
End user devices and servers are often 1 ip away from each other. We can subnet the IP range into smaller blocks.
Options: Besides changing the IPs on all the PCs or all the servers, what are my options?
Thank you,

Thats alot of devices left...
The server ips would have to stay since changing those ips would be a bigger headache.start with the least amount of static devices and work your way up. Do the ips on the other site overlap with your current scope (s)?

The remote site doesn't exist yet. so, the IP range can be anything we want. We found out that our datacenter is to be migrated in the next 90 days. I'm trying to come up with the easiest idea for a temporary fix regarding the servers and other devices being on the same IP range. If there is a way to use the same ip range across two sites that would be a good temporary solution.

Ultimately, we made over a dozen new IP ranges with VLANs at the existing and new site. The PCs as advised were easy to update by changing them to DHCP via GP. The 200 other devices (half of which were printers) had to all be touched manually and at times required the vendor to be involved. For the routing we used two ASA firewalls (a lot of hair pinning) and ultimately it worked out.
