Hi Gents, so i replaced my Cerbo Box in June, because i had some serious stability issues with the old device which even could not be solved with a factory reset. Since June i have a new Cerbo and also a new VRM Portal-ID and a new VRM Installation. This morning i saw, that i can replace my cerbo box in the VRM Settings of the old installation. What exactly happens if do this? Will the old VRM Installation continue to run, but with the new Cerbo box and merge all the data of the Old and New Installation? ---

If you move the GX, it will use the new gx to log to the old (replaced) site. But will stop logging to the new one. (The one it is currently one) It won’t migrate what has already been logged on the new site. ---

When trying this procedure, I get ![image](https://europe1.discourse-cdn.com/victron/original/3X/6/6/6639af4ddbd65969098e084c9ae5676e8a96980b.png). Do I need to do this procedure with the new Cerbo before doing the replace procedure on the old site - ![image](https://europe1.discourse-cdn.com/victron/original/3X/4/a/4ad04721254681602c3b3aede787e2fe4abea684.png) ---

I do not know if you have seen the manual for VRM, here is the GX device swapping instructions. > **[14. Replacing a Victron GX device in VRM](https://www.victronenergy.com/media/pg/VRM_Portal_manual/en/replacing-a-victron-gx-device-in-vrm.html)** ---

Thanks for quick reply. It is what we’re trying to do, but the process stops before we get to step 5. Here’s what we have done in more detail: One of our installations in Malawi stopped working properly. Our installation team physically replaced the cerbo, added the new cerbo to a new installation in VRM. After having left the site where the installation is done, the team (and I) have tried the process in the manual, but the process fails with the message in screenshot 1. Not clear to us how to proceed. ---

We got this solved by reaching out to our Victron reseller that triaged directly with Victron, hence was solved by Victron in the backend ---

I have the same problem while replacing a Cerbo S with a Cerbo GX MK2. I get to step 5, but it does not show the replacement device on the right dropdown (replacement device). Nevertheless, when I go back to “All Installations” the new one is shown. I can start the process all again but then in the replacement workflow (first formular) I get the notice that the Cerbo is already used in an installation (same as @espen.overbye above). I did the whole thing a couple of times including deleting the ID from my account and restarting. no change. I feel like I am in a hamster wheel …
