Yes if the chip architecture is the same, no otherwise. Your problem
here is a thing called "Endianness". i86 (the Intel architecture) is
"little Endian" while the Motorola chip architecture is "big
Endian". (It's to do with which "end" (or side) the significant bits
are stored on.)

A read of the documentation would quickly lead you to the right
answers. Without giving intense details (which you need to study)
you create a transportable gbak backup under the Windows server for
the database you want to source from, then you use gbak on the
destination server to restore the gbak backup.
