hi everyone,

we got version operator version 2.2.5 running at this point (yes i know we are running behind)
and i want to update it to the newest version.
but i would like to know how safe is it for me to update to 2.3.4 straight away.

does it have a rollback options if it fails?
which backups should i make to guarantee i don't miss any configuration.

is it best to update in smaller steps?
if so which updates steps do you recommend? and where can i get the update files?

do any of the updates touch the Host file? cause we changed it for some dns adjustments.

hope to hear from you.
thanks in advance.

You can make full backup (all checkboxes) of your current version. If you have too big logs or to many recorded calls etc. sufficient should be:
- system configuration
- ssl certificates
- license and
- cust. prov. files /var/tftp

Those four checkboxes are Operator's "configuration"...

Then try to upgrade throught 2.3.0, e.g.: 2.2.5 -> 2.3.0 -> 2.3.4

All versions you can find in our SW archive:

If all passes well, you can make new backup, delete old one and start with new Operator.


Otherwise find version 2.2.5 in SW archive and try to downgrade back using "upgrade" image ("Kerio Operator upgrade" item) or reinstall whole Operator ("Kerio Operator rescue flash image" item). Then restore your ORIGINAL backup.

Have a nice day!
