# Server Upgrade - Verify Accounts

Before you upgrade Tableau Server, verify that the account you will use for running Tableau Server Setup has `sudo` access.

If your organisation uses an external identity store (LDAP or Active Directory), then it's a best practice to have the credentials or the keytab file for the account that is used to bind with LDAP.
