general IDS 10 FC9 install questions?

Hey everyone. I have some basic IDS Fc9 install kind of general questions... I have tried finding answers on this and believe it or not have not been able to.... Has anyone installed IDS 10 FC9 on any unix machine? If so do know what the size of the informix install tar file is? I need to get this so I can determine how much staging disk space I need. Also....The system I am installing on uses Enterprise Replication as well as hacmp software for failover. The install manual says I will need to run some conversion script for the replicated tables when going from the current version IDS 94 FXC21 to IDS FC9...Besides this are they any special considerations anyone is aware of regarding the replicated tables? Any gotchas to look for? For the failover this systems uses hacmp IBM software. I have not heard or read anything about needing to have any special concerns about this with regards to the upgrade. Are there any 'gotchas' anyone is aware of regarding the failover software? I know a bunch miscellaneous questions but I have some difficulty getting the answers to these and would like to do as much prep/planning as possible. Yeah I know...installing/upgrading Informix is no big deal. I guess I am just paranoid. Anyway...thanks. Will
