I have installed the latest eggdrop to a very old version of eggdrop with a user file from like the mid 90's. I try to share the user file to new eggs I install and it connects fine if I have them both set for passive, but when I try to set all the leaf bots as +s from the hub bot with the old user file, it connects and then dies after trying to send the user file. Do I have to convert the old user file somehow? Is this a known issue?
Since you dont specify your old eggdrop's version number, all I can tell you is to read the part about upgrading in the README file in your eggdrop root dir.
You can (somewhat) convert a older userfile to a new one using the weed script in you scripts/ folder.
Again, its explained in detail in the REDME file that comes with your eggdrop.
