world, perhaps. There it is possible to restore on Windows from backup
made on Linux/Intel, of from AIX to Solaris. But, probably due to
Little-Big-Endian issues it is not possible to use backup made on AIX
to restore on Windows. And the backup engine and restore engine do not
have to be the very same release.

Regarding backup/restore, some innovation could come from DB2 LUW world, perhaps. There it is possible to restore on Windows from backup made on Linux/Intel, of from AIX to Solaris.

but I would gladly accept it. The real issue in Informix, could be the
different page sizes... Everything is a page. But a page can be 2K or 4K.
Transform 2K pages into 4K pages or vice-versa would be a nightmare...
Regarding the need to have the same exact version I would also accept it
peacefully..
Of course there are probably a lot of issues that I'm not aware...
Regards.

the same basic type of chip. HDR between PA-RISC and Itanium would not
be supported.
ER does not require the same platform.
