# Server Upgrade - Verify Licensing Status

Prior to upgrading Tableau Server, review the product keys that are currently installed and compare them to the product keys, maintenance expiration, and licence expiration end dates that are listed in the Tableau Customer Portal.

It is important that all expiration and end dates associate with product keys are up-to-date before you upgrade.

**Step 1: View licence expiration information**.

Run the following command to view all licenes that are installed on your Tableau Server installation:

tsm licenses list

The [tsm licences list](https://help.tableau.com/current/server-linux/en-gb/cli_licenses_tsm.htm#TSMLicenseList) command returns all licences, each with a number of fields. For upgrade, you need to make note of two fields:

- For each subscription licence, make note of the date in the LIC EXP field. LIC EXP displays the date that the licence expires and Tableau Server will stop working.
- For each legacy perpetual key, make note of the MAINT EXP field. MAINT EXP displays the date that the maintenance contract for the Tableau Server deployment expires.

Step 2: Compare licence expiration dates from TSM to your licences in [Tableau Customer Portal](http://customer.tableausoftware.com/).

**Step 3: If required, update licences**.

If your TSM maintenance date is not current or the expiration date will occur soon or is not the same as the date listed in the Tableau Customer Portal, refresh the licence.

To refresh the licence:

1. Open TSM in a browser:
    
    http://<tsm-computer-name>:8850
2. Click **Configuration** and Licensing and click Refresh All:

If this does not update the maintenance or expiration end date but the Tableau Customer Portal does show more current end dates, please contact [Tableau Technical Support](http://www.tableau.com/en-gb/support/request).

Reactivating the product key will be part of the upgrade process.
