We have two CAM and two CAS appliances. Both pair of them are working in High availability mode.
We need to upgrade them from version 4.1(3) to version 4.7(1) so, as i read, we should upgrade them to 4.7(0) first before upgrading to 4.7(1).
Now, i'd like to know how can i upgrade from 4.1(3) to 4.7(0)? Is this done by the same steps of the upgrading from 4.7(0) to 4.7(1) by inserting a CD into the CAS and CAM and then continue the upgrade steps?
Also, I'd like to know if the configuration on the existing version (4.1(3)) will be lost after the upgrade or not?
Thanks in advance.
4.7.0 and 4.7.1 both require CD installs, that is, you will have to put the CD of 4.7.0 first, reboot and get that going.
Once it's on 4.7.0, you will have to put in the CD of 4.7.1 and do the same.
Both the upgrades will give you the option of upgrade, and when you choose that, you won't lose your databaes or settings.
