Tool for config backups and mass config changes / Any recommendations?

Hey guys,

I'm looking for a tool (open source or paid doesn't really matter) to backup our network devices (mainly HPE / Aruba switches) and do mass config changes/rollouts. Any suggestions?

We only have around 30 stacks (2-4 switches each) on three sites.

​

Sorry if there's already a post about it, but I haven't found anything recently in this sub.

Btw, this is my first post in here. IT hooray!

​

Thanks for your help!

Cheers, uneinverleibbar
