Cloning an environment

We have an Informix (7.22) on AIX environment and recently installed an evaluated version of Legato Networker. Now onbar functions fine. However, we want to "clone" this environment to HP (10.20) also Informix 7.22. Questions: 1. Is onbar able to restore archive to different platform (AIX->HP)? I'd probably think no, but would like some input. Because AIX is 4k-page and HP 2k-page. 2. What about using the Replication feature of Informix 7.22? But I've no experience on this, can someone tell me the steps to put this to work? 3. We don't want to use dbexport/import c'os it takes > 8 hours to do it and we have only a window of 4-5 hours. 4. We also don't want to use "insert into tbl select *" because the time to rebuild the indexes and perform an "update statistics" would probably still takes ~6 hours or more. Thanks. Chris
