Hi,
I have sun enterprise server which uses an lineox box as its mail server and for also storing backups. the mail is linked from the lineox box to sun server and theres a mount on the sun server linking the box for partition,
I want to get rid of lineox OS and install solaris 10. But i want to keep my old var/spool/mails for all users and also the backups...
is there an easy way to proceed
please advise
Just curious -- I've never heard of the Lineox Operating System -- care to share the source?
Also, to answer your question -- no you cannot "Upgrade" from any particular OS to a completely disparate OS. If it were an older revision of Solaris, yeah you could upgrade, but not from "Lineox".
If you want to retain your mail spool, back it up -- make a simple tarball --
# cd /var/spool
# tar cvf /tmp/mailspool.tar mail
Make sure that /tmp has enough space to accomodate the mail spool tarball. Similarly, back up everythign else you want (if you have a tape drive and some tapes, back up to tape).
Then if you have a mirrored root disk, blow away the mirror and install Solaris 10 on it. That way you can always revert back to the original OS in case the upgrade doesn't work or you're not satisfied with the installation.
Also, before you try to "retire" or migrate functionality of/from a server, it is very important to know EVERYTHING the server does. Often times, it might be too late to go back and fix things (especially in case of legacy, unsupported/unsupportable infrastructure). So my advicei is to study the system carefully and ensure you know everything it does.
Create a table in your favorite text editor. Punch in the following columns:
functionality|component
Check whether those components/functionality are/is available on your target platform. If you have a spare server to test., play with it and make sure it's usable.
