upgrading a linux virtual server

[jdd]

Hello,
I plan to update my web server doing the following:

* make a snapshot
* change the linux repositories
* make the upgrade

once I'm sure all is nice, delete the snapshot

is it the good way? nothing forgotten? (I have all the space needed on
the disk)

thanks
jdd

Since I'm paranoid and I know that "if something can go wrong, it
will" ;-) I'd go the extra mile and create an archived backup (perhaps
compressed with 7zip / p7zip, using maximum compression -mx9
parameter) of the .vdi / .vdk or whatever disk image file you're
using, before making the upgrade.

Just in case, you know. ;)

Exporting the machine in its current state as an ovf "appliance" and
storing it on another (perhaps external) hard drive is also a good
security feature.

But the above is just adding layers of redundancy. "just in case" ;)

So, yes, I can't think of anything else besides what you proposed for
a Linux distro version upgrade...
