On premises to hosted, confirming process.

[Earthbound]

From what I have read in the forums and learned via research, as follows, please add any corrections needed.
1. Create a new cloud instance in our account.
2. In that cloud instance: create the storage location.
3. Create a backup, not to exceed 3GB of our on premise 3CX system.
4. Load that backup into the storage location created in the cloud instance.
5. Log into the cloud system and restore the backup from the storage location.

Question: What settings in the on premise should I change/remove pre-backup?

Thank you in advance for your time and energy!
