Preparation before the actual upgrade:
1. Getting the installer:
a. LiteSpeed Version 6.0 and above are available for download at https://support.quest.com
after logging in with your registered user account. The msi files are specific to 32-bit, 64-bit and 64-bit Itanium, the correct version will be the same as the bit version of your SQL Server and processor version.
c. Refer to the Installation Guide which includes upgrade steps.
2. Getting the new license:
Version 6 of LiteSpeed for SQL Server and above uses a new licensing system that requires upgrading LiteSpeed version 5 license key formats. To obtain a new key, please go to this link: License Key Upgrade and follow the instructions. Old license keys will not work with the 6.0 version. Please obtain your new license key prior to upgrading to LiteSpeed for SQL Server version 6.0. If you have any questions concerning your license keys, please contact our Licensing Department. https://support.quest.com/LicenseKey.aspx
3. Performing the upgrade:
Refer to the installation guide for details on upgrade. Here is a summary:
a. Before installing a new version of LiteSpeed, disable any LiteSpeed jobs (including Log Shipping jobs) that are scheduled to run at the time of upgrade on all servers where you plan to upgrade LiteSpeed.
The Publishers need to be on the same version of LiteSpeed as the Subscribers, so the upgrades should be performed at the same time.
b. Run the installer, follow through the installer wizard to upgrade.
