Looks like I'm adding complexity to an already complex project...
In the server move that I spoke about in an earlier email, I am now
upgrading the OS as well. So I will be moving a 7.4.4 installation
from a RHEL3 to a RHEL4 server. In the DR Guide, I'm a little
unclear about whether this can be done with mmrecov or not:
Yes, you can move from RHEL3 to RHEL4 via mmrecov if you really need
to. (Generally speaking this is why it's a good idea to keep /nsr as a
separate partition - that way you should be able to accomplish most OS
upgrades without needing to perform any disaster recovery activity.)
The only thing I *would* caution about is changing bitness - i.e.,
going from RHEL3-32 to say, RHEL4-64. If you're going to do that, I'd
suggest more caution, and possibly a test environment.
Cheers,
Preston.
