Thank you all mates for your replies.
the thing is we are talking about a size of 12 TB in total, no free space to assign on the X86 server to restore to, so I need to use same lun in something like export/import.
The ZFS option would be good to apply on the X86 server, but I dont think there would be a way to preserve the data on the same luns while they are being converted to ZFS.
If this can be done, then I can convert them on the source ( sparc server) then move/map/mount them to the destination ( X86 server), Do you think that would be possible?
Seems the only possible solution, is to backup everything to tape, then re-format the luns on X86 format, then restore back from tape, which will be so time costly off-course.
Regards
Aladdin

I know that Sun make s a version of Solaris for Sparc platforms and also an x86 (Intel/AMD) release of Solaris. Can an application that runs on Solaris/Sparc also run on a PC running the x86 release of Solaris? Would a different release be required or any re-compling of the application?
