Downgrade WSA from 15.x to 14,x

[TVmaster]

Hi Fellows 

it it possible to downgrade a new WSA that came from factory with 15.x version , to a 14.x version?

i cant found any doc with this procedure ou even a Reimage the WSA. Revert process is not considered because it is a new WSA...

My SMA is 15.0 , and all my WSa is 14.5.1... .this new WSA came with 15.2... and i need to downgrade this new one...

thanks

If you like to downgrade you can do from command level

WSA > revert and choose the version to revert back WSA.

before you doing, make sure you check the following.

1. confiuration backup done from WSA and SMA  (password unmasked)

2. make sure SMA is compatble matrix the one downgrading.

3. on SMA you may need different config master 14.X since your config master now 15.x so you need to take care of that.

4. if you have changed any custom pages take the backup that files.

If you have register with smart license then unregister before downgrade and after downgrade.

Option 2 :

If you have known config of 14.X , then you can do factory reset and restore the backup.

He can't revert it...
Brand new box, imaged with 15.2 at the factory, so there's no old code to revert to.

Good catch, i may have missed bit, cheers!

You're going to have to upgrade your SMA at the very least...

WSA 15.0 and before isn't supported on the x96 boxes (assuming your brand new box is an x96). The first version supported on x96 was 15.2.
