David,
if your tests are successful according to you then why you are worried..
if upgrade path is proper then then the migration is not difficult..
I would have chosen 8i(in 8i mostly you are using dictionary managed tbs
and rbs, system and internal user) to 9i (first time oracle introduced
asm, undos, rman, sys user with sysdba and sysoper..list pl correct me if
am wrong) with tbs migration and then from 9i to 10g (10204 is more stable)
or 11g
hope you also have a proper documentation of parameters used in 8i db and
to be used in 10g or 11g
also hope you have a proper documentation of grants, privis, roles used in
8i and to be used in 10g or 11g
many of the parameters, grants, privs, roles are deprecated..you need to
take into account this fact..
Actually, this can be an exciting project, do not look at it as a insane
migration..look at an opportunity to regenovate your application with very
much advanced features, Technic, query enhancement, architectural
changes..surely a feather in your crown..
only I would like to ask you is you have not informed about application..if
it is 8i then have you checked whether it can be still used using 11g..
thanks..subodh
