hi pelayo_53637,
Thanks for your post.
We are aware of this architectural flaw and for now the only most effective way is to edit your automation script in text/xml editor (eg. Notepad++) and simply lookup the connection data and do replace... If it's just IP address /hostname then it might be easy.. I believe once you open it you will see it.
Also please backup your scripts before doing so!
Let me know if you have a problem with a specific activity and how to convert them.
