Hello Pri aka @PriyankaNath
Apologies for the delay in response! I spoke with one of our TAC representatives regarding your post and this was their response:
If you are running what we call a "software install", where the traffic manager application is installed on top of the Linux distribution of your choice, you can upgrade between versions very flexibly. I'm not aware of any restrictions. You could jump straight from 9.0 to 10.4r1 (for example) in a single step without issue. The procedure can be found here:
If you are running a virtual appliance, then the upgrade conversation becomes more complicated. The size of the disk was expanded in version 9.7. So in the scenario you describe on a virtual appliance, if you jumped straight from 9.4 to 10.4, the device would come up in an unsupported state. Fortunately, the process to correct for this is simple enough. Here is a quick summary:
Take a hypervisor snapshot of all existing virtual appliances in the cluster. This provides a safe fallback if something unexpected happens.
Take complete backups of all existing virtual appliances in the cluster.
Turn up brand new virtual appliances at the desired version. (10.4r1 or whatever you've selected)
Import the backups from the previous version into the new machines.
There are a few more considerations, the steps above are a summary only. The complete version can be found here:
We hope this helps!
