Migration
Let's talk about migrating your panel between servers. It doesn't matter whether you're switching hosting providers or just moving from localhost to your own custom domain.
During migration, do not install a newer or older version of CtrlPanel on the new server. Always install the exact same version as your current one. Otherwise, you may run into compatibility issues.
Backup your database and .env file
Never lose your .env file, more specifically, your APP_KEY. Without it, you'll lose almost all data that Laravel encrypts in the database using this key.
We have a separate guide on how to back up your database and where to find the .env file. You can find it here.
That's all we need - just SQL file of your database, and .env file with your APP_KEY.
Preparing new location
Follow the default installation guide and complete all steps up to the final one - "Navigate to the installer". Once you reach that point, come back here.
Database migration
Now we need to import the data from your .sql file into the database on your new server. You can follow this guide to do it.
After that, place your old .env file into the CtrlPanel root directory (/var/www/ctrlpanel/).
Update the database password or other values if needed, such as APP_URL or APP_NAME.
Lock installer
Now create an empty install.lock file in the CtrlPanel root directory (/var/www/ctrlpanel/) to disable installer since we don't need it anymore.
touch /var/www/ctrlpanel/install.lock
Finish
Congratulations! You can now try opening your CtrlPanel page in the browser and check if your data was successfully migrated.
