Hi @khineminn
I want to join to @the_rock and I want to explain with my words too 🙂
You said that, you want to know from the MGMT server point to view:
If the MGMT is not a VM (e,g, VMware) I always use system backup because it contains all of the necessary things that I need for revert. I do tests on MGMT ant LOG server the steps are the following:
- I make a system backup and save it to an another location
- before I do the next step I make and md5 hash on both side -> ensure the hashes are the same
- I reinstall the appliance (or open server)
- install the JHF what is required
- upload, and restrore the backup file
- test it, test it, test is
Don't forget, the backup does not contain the logs!!!
If you have time, do this steps in a LAB, and you will be confident in live situation 🙂
