All you have to do >> is to copy everything (frm, arc, 4gi, dbs, etc.) to the AIX machine, ^^^ *Don't* do this. Never copy the database files themselves from one platform to another; they can have architectural differences (e.g. different index node sizes). The proper method is to UNLOAD from the source machine and LOAD on the target. dbexport/dbimport can be used to automate the process. If you *had* to copy, you should follow it with a bcheck of all table files. Index nodes can be resized if necessary using the -s option. Even so, I wouldn't advise this method, and it's not supported. >> load your new Informix and run it.

Always recompile if you have the choice. Sometimes, you outright have to recompile (e.g. moving pcode to RDS 4.1 which has report functions). If you are moving pcode to another platform with the same version of RDS, recompiling isn't necessary. >> In our office we develop using 4.0 on the RS/6000, but some customers >> have 1.10 under SCO and everything run perfectly!
