We are in the middle of a building move and IP schema restructure. In the interim we are also planing on upgrading CM 4.23 to CM 7.x. If we decide to migrate now to CM7 will it be a problem changing the IP addresses of the SUB and PUB later down the line when we finalize our IP schemes?
I heard that it will not be a problem to change it but can create many problems down the line and eventualy paralize the system? Which is it? What kind of things should we look out for? Should we just do the upgrade after the IP scheme is finalized?
