# How to Use QGIS Plugin with Multiple Servers
There is a default server app.merginmaps.com which is configured in Mergin Maps plugin for QGIS. However, in some cases you might want to use some custom server, e.g. when you host it yourself.
# Custom server configuration
If you want to use a custom Mergin Maps server, you will need to configure it in Mergin Maps plugin for QGIS.
Click on the Configure Mergin Maps plugin icon to open the configuration dialog
Check the Custom Mergin Maps server option and enter your custom server URL.
Now, the server URL is saved in current QGIS profile settings. So whenever you open QGIS with this profile, the Mergin Maps server is associated with this URL.
# Migration between Mergin Maps servers
You might have started working on one server (e.g. staging server, official cloud) and then you decided to migrate to a different Mergin Maps server. If you change a server URL as in the config above, you will be connected to a different server and this option will hold in subsequent QGIS sessions until you change it again. This way you can switch between servers for a single QGIS profile. All projects for all your servers that you downloaded to your computer are still remembered.
Plugin will not allow you to migrate projects from one server to another. Your local copies are already associated with the server they were downloaded from. If you really need to upload your local project from one server to another you will need to create a copy of that folder elsewhere (without hidden folder
# Using multiple servers simultaneously
If you need to handle two different servers at the same time, you will first need to create two user profiles in QGIS and download Mergin Maps plugin for QGIS for both.
Then you can configure Mergin Maps plugin for QGIS for each of them using different server URL. Each session for given user profile will be connected to its own Mergin Maps server as specified in the plugin configuration.
The limitation for transferring projects between servers still holds.
