Converting 3digit extension to 5

[PBXJay]

Hello all.
We are converting from 3 digit extension to 5 digit.
I just wanted to make sure I have everything covered.
-I've contacted our phone company to make sure all our toll numbers have the new 5 digit DNIS pushed
-I'll need to update our dial plan
-Need to change all the 3 digit extensions to 5 digit including stations,hunt groups etc
-Change all of Intuity extensions to match
-Change intuity auto-attend routing to 5 digit.

Have I missed anything?
Also, do I need to change the TAC and FAC or can I leave them as 3 digits.
