Enterprise Replication systems
It states the systems must be homogeneous..what happens if you need to do an OS update (upgrade levels) or even update the IDS? Do you have to take all systems down to do this? Also, I read something similar for HDR...is that the same?

This may or may not change in the future.

For HDR a.. Both servers must run the same Informix version a.. Both servers must be able to run the same Informix executable. Ubuntu and Red Hat run the same Informix executable, HP/UX and Red Hat do not. a.. Both servers must have network capabilities a.. The Secondary server must have at least as much disk space for dbspaces as the Primary. The dbspace chunk types (cooked or raw) do not have to be identical a.. Dbspace chunk path names must be identical Enterprise Replication does not have these limitations, you can replicate from a 64 bit Unix box running IDS 11.5 to a 32 bit Windows box running IDS 10.0, or in the less severe case you can replicate between two servers running different upgrade levels.
