Restoring a backup

[luhrern]

I have several Z-WAY setups. TWo of those are 5-6 years old and I want to update with Raspberry 5 and Raspberry Pro with antenna. The hardware has been purchased and shipped, and will arrive the coming week.

I am curios how to migrate the current systems to the new hardware. Is the solution to 1) create a backup in the Z-wave Exprt UI 2) install the new Raspberry PI 3) install a brand new Z-way instance with teh new Raspberry pro 3) connect to Z-way 4) go to teh Expert UI and restore my backup ?

For the current setup 1 - I have managed to upgrade to teh firmware v.4.1.4 before I did a backup

For the current setup 2 - I this is a older firmware as I did not suceeded to uprgade - can this be a problem ?

Nearly right.
From the Smarthome UI - Settings - Backup & Restore
Do the backup and restore from there. the .zab file contains everything. Expert ui backup (.zbk) is not needed.

Much appreciated - do you forsee any problem with such a migration scenario what I have not been able to upgrade my current Z-WAY controller ?

I would install the zab backup at last. There's no sense to start the user software before everything else is ready.

My proposal:
- for security upgrade system2 to a later version, for example 4.1.2. Razberry 7 needs at least 3.2.3.
- do both backups (zab + zbk) for both systems.
- install the new systems (OS + Zway) + upgrade to the latest versions
- upgrade the Razberry 7 firmwares to the latest version
- install the zbk backups in Expert UI
- check config.xml + /etc/logrotate.d/z-way-server + .syscommands if you have made some changes there
- install the zab backups
- check if all your modules in UserModules are there
If anything is missing, copy it from the old system
- if your modules store anything to the storage folder and it's missing, copy it from the old system

Do you really want to switch to Raspberry Pi 5?

There is always confusion about what the two backups contain. To clarify this question once and for all, I have now searched the documentation

zab-backup (from ZWayManual.pdf, chapter 4.3 The Management Interface):

Please note that the backup and restore function will only handle files on the controller, and not the Z-Wave networktopology stored in the Z-Wave transceiver chip.
To overwrite this content, please refer to the Z-Wave Expert User Interface , as described in Chapter 7.5.1.

zbk-backup (from ZWayManual.pdf, chapter 7.5 Network):

The backup file is stored on the local computer.
Please note that any restore will overwrite the existing network. The restore operation must therefore be confirmed in another message box. A checkbox defines if the node information in the Z-Wave chip itself will be overwritten as well. This operation result in a possible loss of all network relationships and may require a re-inclusion of devices.
Handle with care!

and in more detail:
zbk-backup (from Z-Way-user-manual.pdf, chapter 5 Network Management):

The backup and restore function allows to make a backup of the whole configuration of Z-Way into
a file. The backup will include all included nodes with all their values, status and configurations
as well as all rules, scenes and timer.
The restore function will overwrite all node values and configuration and automation settings.
By setting a checkbox the restore function will also overwrite the network topology information
stored in the Z-Wave chip itself. This will change the home Id of the controller to the home
ID stored in the backup file. This means that the new controller is an identical clone of the
controller where the backup is from.
This function needs to be handled with extreme care. Running two identical controllers in
one network will certainly screw up the settings of both controllers if not doing any further harm.
Make sure that there is always only one copy of cloned controllers active.
The backup and restore function can be used to move the network between different imple-
mentations of Z-Way.

Thankyou for all advices and explanation. And that is was pointed out that to use a PAsperry PI 5 is a no go.

I have Z-Wave.me normally installed on a RP5 32-bit OS since February. There was some issue with the 64-bit OS. I don't remember if it was also with Z-Wave.me, I don't think so, but definitely with another application that I use. That's why I only run a 32-bit OS.

Interesting.
Does this mean, are you running Z-Way on a Raspberry Pi 5 with 32-bit Bookworm? Is it working correctly and did you have to do any adjustments?

According to Z-Way documentation, Bookworm is still not officially supported:

The Z-Way team still seems to be working on a version for Bookworm:

Yes, exactly as you wrote.
