I have a vera plus and for a few days the zwave modules have not been seen. 9 out of 10 zwave requests do not lead to the module.
rfx module has not problem.
If I try to integrate an existing module, the vera can see that the node already exists. I withdraw it: ok. I include it again: ok. I test by throwing on / off: node “non-existent” …
I reset the veraplus then restore an old backup: still the same problem.
I tried to contact vera support but I think the company has gone bankrupt 
here some logs:

I have a 60th of modules and a lot of scenarios, and nothing works anymore.
If no solution is possible, there are migration tools to switch from vera to another box from a backup (so as not to have to rewrite all the scenarios and scripts)?
Thank you for your help, it is a big real problem
