Recover Database complains of version

Question

This is not technicaly a RMAN question but it seemed the most appropriate forum.
I am testing some database recovery scenarios so I know what I'm doing if I have a real problem.
I have a database that I have replicated to another machine and have current control files and archive logs, but am restoring an older set of datafiles to try and recover using the archive log information.
The archives were created on another server, but I have tried to mirror that install on a nother system. I have restored the control and archive log files from a more recent "hot" backup and the datafiles from an older "cold" backup. When I attempt a manual or auto recovery I get the following error:
ORA-00331: log version 8.1.0.0.0 incompatible with ORACLE version 8.0.5.0.0
ORA-00334: archived log: '/var/opt/oracle/admin/ORCL/arch/arch_1_34963.arc'
Both this instance and the instance that created the original files were backup up from are running 8.1.6.0.0
Any ideas why I would be seing this? I did a similar test about a month ago with no problems, I can't figure out what is different. Here is a log of the session: Sorry if the formatting get's mangled)

Dennis,
What about the compatible parameter in the init.ora? What is it set to on the new host?
Thanks.
