IP addressing scheme change
Hello,
A client has a single location network spread across several floors. The tech they had earlier configured their network with a class A 10.0.0.0/8. They've run this for a decade and are now looking to make it more efficient. They only have 300 users, a couple of hundred other devices like printers, scanners, UPSes etc on a single VLAN. They do have a DMZ VLAN with its own class C 192.168.0.0/16. They are planning on bringing in VOIP on its own VLAN (IP scheme undecided yet). It's a Cisco shop with ASAs and catalysts running the network.
What would be your suggestion/plan please?
Thank you.

Keep using 10.0.0.0/8. There is no reason to limit yourself by using a different range

Thank you all for your valuable input. I did want the VOIP on its own VLAN.
What all would I need to touch to ensure that if I decide to go with the /8 to /23 change? Each statically assigned device, firewall, switch etc would need to be reconfigured.

Yep and then new DHCP scope and reset all dynamic devices.
I would not go with a /23 as you say you are already at 400 plus devices, so a bit of growth will put you over 512 - why plan to cause yourself more work?
I would at least go with a /22 or even /21 to allow for plenty of growth.
If you are splitting into smaller VLANs then that is different.
