Thank you very much for the help.

my package.json file had * for the lightstreamer-adapter version. So when re-installing the server the adapter was upgrading thus making it incompatible with the server version of LS.

running npm install lightstreamer-adapter@1.0.2 resolved the issue.

We wold very much appreciate some tool to help the porting process, for now we will continue with our current setup which is otherwise working fine

Thanks again.
