Upgrading 2.5.1 to 2.6

[grega]

I have to do this in the near future. We have a very simple setup - 1 Ultra Sparc with 2 external SCSI disks.

I am of the opinion that I'll do a full backup to tape, take additional backups of all critical files, shove in the 2.6 CD and take it from there. Hopefully all will go well.

I just thought I'd throw the question to the floor anyway ... Are there any "watch out for this!" points from anyone who has done this upgrade?

Every time have done this upgrade, I haven't really upgraded, I've installed a fresh version of the OS on a newly formatted disk.
The differences between 2.5.1 and 2.6 are really quite substantial, so the potential problems in upgrading are many.

Since you are going to backup all your essential files, why not restore those files, after installing a fresh version of 2.6.
OK, it will take longer but you know you're getting a 'good' version of 2.6 and you know your files are safe. Ian

"IF" is not a word it's a way of life

Thanks Ian, not really what I wanted to hear :-( but I'll look into it.

i've done it ... and although Ian is right, it does upgrade ok ... but only as long as there is enough space on the drives ...

done it twice and the first time was on too small a slice for usr i think ...

btw it's a very painful process to let solaris install try to back up and restore for you if this happens ...
