Update Satellite - Backup & Restore

Hello,

we have a single satellite server, running on an rhel7 vmware based virtual machein. All client configuration management and patching is running nightly, so i want to update from Satellite 6.6 to 6.9 during daytime. My plan looks as follows:

1. Shutdown satellite services and vm
2. Create a full vm backup (vmdk)
3. Start satellite
4. Update satellite
5. In case of fire: Destroy current vm and used the backuped one from step 2

Will this work? Anything else that i missed in my considerations? I havent found this type of backup in the docs, but i think in my case its the easiest and fastest way.

Kind regards,
Sascha
