I currently have a local network running on the range 192.168.50.0/24, but I am running out of IP addresses to use.
The plan is to change the network to 192.168.50.0/23 network, which will effectively double my address space, giving me a range of:
192.168.50.1 - 192.168.51.254
I would like to do this migration in a phased approach, if possible. There are many devices that are served by DHCP, while many others have been assigned static IP addresses (and require them to be static). Several devices with static IP addresses can only be changed by a 3rd party supplier, so it will have to be done during business hours, on a live and in-use network.
My question is - what will happen during the transition phase, while changing IP settings on the various devices? Will things break? Or will communication still be fine between the existing /24 network and the new /23 network? Traffic won't be crossing any routers, just several switches.
What is the best way of managing this transition on a live and in-use network, while trying to minimise potential downtime and other issues.
