Upgrading

To learn which License Server version you have and check for updates, see Check version. Before upgrading, make sure that your environment meets the requirements. To learn about the latest features, see Release notes.

Upgrade your FLS installation

Save the conf folder from your current installation somewhere safe and back up your current FLS installation directory – for example, as a ZIP archive.
Change to FLS installation directory using the command line.
Use the following command to stop FLS:
./bin/license-server.sh stop
Empty your current FLS installation directory.
This step is essential — leftover files from a previous installation can prevent FLS from working correctly.
Download ZIP archive and extract it to the FLS installation directory.
Put back the conf folder you saved at step 1.
Start FLS using the following command:
./bin/license-server.sh start
Make sure the server still grants users the licenses they request, just like before the upgrade. This confirms your existing registration is still active.

The upgrading is similar to the new installation. You need to repeat the whole process of configuring your instance of FLS and link it to your company profile. After registration, new FLS will take license information from JetBrains Account.

Upgrade your FLS installation

Stop your FLS using the Services Microsoft Management Console (MMC). To open it, go to Control Panel > Administrative Tools > Services > JetBrains License Service.
Download MSI Installer.
Run downloaded MSI installer and follow wizard steps.
Start FLS using the Services Microsoft Management Console (MMC).
Make sure that server grants users with requested licenses as it was before the upgrading. It means that existing registration is in use.
