Hi all, was digging and didn’t find the information I was looking for 
I will be getting the Cerbo GX soon and need to migrate from Venus GX to Cerbo. Also need it connected to the Victron VRM portal (which I believe will be automatically done)
Is there any easy procedure/hints to do this? 
Any curve balls I should be aware of?
Ill phone you quickly… Cant type now
Thanks for the call and explanation Jaco!!
Once I get Cerbo, I will take screenshots and post here for future reference
Bringing up old discussion. My situation is a little different.
I am running Venus on RPi 3 which is running fine for more than 2 years now with Venus OS v2.87. I want to upgrade to the latest Venus. I have several custom scripts (together with the serial battery driver) and settings (some of the related to setup helper and related stuff to it).
Which is the best way to jump to the latest and preserve all custom stuff?
Since the system is running fine I am contemplating preparing a new sd card with the latest Venus flashed and transfer the data from the running system to the new sd card, then just swap them on the RPi. However I suppose I should be careful with the transfer stuff so I do not break something.
The other way would be to power off the PRi do a dd to the current sd card to an image (backup) which I can burn later in case of need. Then I can return the current (old) sd card to the RPi and continue with the upgrade path from venus os interface. However this means I will need to pass over several upgrades to reach the newest version. As I remember all data is lost during upgrade, so I will need to set up everything again, including installation of the serial battery driver, right?
What would you recommend in my case. Is there way to easily transfer settings?
What is happening with the system in case I power off the GX for maintenance?
Is there any recommendations for example to switch off chargers, have some min battery SOC, etc?
The system is simple: Multiplus II (3000/35/48), SmartSolar 150/35, RPi (GX) and custom battery bank with JBD BMS (100A). The GX is powered from the battery with the aim of two step down dc converters (60V-12V-5V).
OK, the Venus wiki in github answered most of my questions
I will do a venus re-imaging of the latest image to a new sdcard and keep my current one for backup and settings transfer.
Just curious about:

If you use Victron connect from your PC and link it to your VRM profile, you can set up the MPPT to run in Standalone mode. With your MPPT being a smart version, you can use Victron connect on your phone and follow the instructions in the link below. You need to make sure that the charge voltages don’t exceed the battery max charge voltage. You can also ensure that your config file on the Multi is configured correctly through your normal VRM.
Config File: ensure that your charge voltages dont exeed the max allowed charge voltage of your battery.
MPPT through victron connect: Same here. Charge voltage is key.
Victron Connect MPPT setup instructions
After doing that, I would unplug the Can cable on the battery, that might cause a error 67 (If I remember correctly) complaining about the missing BMS, I will then “Reset” BMS control on the Remote console - Device List - Your MPPT - Networked Operation
You can now unplug the Ve-Direct from the MPPT and the MK3 from the inverter and switch off the Pi. The system should run as a standalone system with each component on its own till your done with the PI. This will also safeguard your system in the future should your pi fail.
@JacoDeJongh, fantastic explanation, thank you.
As far as I remember when setting up the system initially I configured separately the multi and the SmartSolar so they can run safely with my battery, however will check this to be sure.
