Upgrade Clustered PMG 5 servers to 7

I have a clustered pair of version 5 PMG's that up for license renewal. I've been debating whether it would be easier to update the version 5 servers to 7 using the existing licenses and also keeping live traffic running through them or if I should just purchase another set of licenses and start fresh?

If I stuck with the original licenses and wanted to upgrade while maintaining traffic through them, what would be the process? Would I need to break the cluster first, take one server down and install a new copy on 7 and restore a backup from 5? Will a v5 backup restore OK on 7? Then install the 2nd server and just cluster it to the first one which will copy all the settings?

Thanks for any advice!

Best regards,
if you want to upgrade from PMG 5 to 7 please follow the guide about upgrading from version 5.x to 6.x [1] and then 6.x to 7.x. [2]. Do not go straight from 5 to 7!

If you decide to re-install the nodes, you need to re-install the subscription keys. How you can do that is described in the shop's FAQ [3].
