Hi, how to upgrade without losing licenses and users already created in older version of license manage to new as new will not accept old licenses.

so in short how to migrate old to new and keep all working as before

Kind Regards

WebLM doesn't check licenses. VMProtectSetSerialNumber does it offline on the end user side.

Hi, thanks for repply.
We not store license on user pc, we check it on each exe start with server(online mode).
Was some reasons what force us to use this metod, and it work super ok.
Problem come with incompability between old and new weblm.
Exist posibility to move "safe" database from old weblm to new weblm keepeng all users , make exe update with new rsa imported from new weblm and new server adress.
But for users must be "transparent" and they use new exe with same serial and same expiration time like before.
Sorry for my bad english.

1. Make backup for your database.
2. Copy new version of WebLM on your server
3. Run install.php
4. Enter name, login, password for existing database
5. Select "Update data tables"

Thanks for your repply, need little help.

Installing first time, we have only "clean installation" option without "Update data tables" option .
After this it ask to create admin and finish.
Executing second time same install.php we have "Update data tables" option also.
But selecting this it ask to create admin also and finish installation.
It not prompt for any sql backup or some like this.
Or need to put sql file in some specific location and give some specific name?

We solved it by phpmyadmin, and all work now.
Thanks for your great product and help.
