How do I upgrade to a new version of Altair SLC?

(n.b. For a z/OS Mainframe please follow the guidance in our z/OS installation guide for Altair SLC.)

Check if you need a new license - see notes below. Make sure your license is ready before you start.

Download the new version from the AltairOne Marketplace website. Workbench and SLC are two separate downloads.

For a single-user Windows PC or laptop, simply install the new MSI. The old version will be replaced by the new version.

If you are administering a server for multiple Altair SLC users then some downtime should be scheduled. One hour should normally be more than sufficient. Follow these steps:

  1. Log into the machine where Altair SLC is installed as the Administrator or root user.
  2. In order to be able to roll back in the case of problems, make sure you have the installation packages ready for re-installing the current version of Altair SLC (or make a complete copy of the current installation files).
  3. Check that Altair SLC is not in use by any users. If necessary, terminate any redundant processes, or reboot.
  4. Make a backup copy of altairslc.cfg and/or altairslc_local.cfg if you have changed them. (Also wps.cfg and wps_local.cfg.)
  5. Uninstall the old version of SLC and then install the new version.
  6. (Re)license the machine if necessary by following the Altair Units licensing instructions. The license utility and documentation are bundled with the Altair SLC release.

NOTES:

MAJOR VERSIONS

WPS 3, WPS 4, SLC 2023, SLC 2024.

Note 1: When changing major version you will need a new license.

Note 2: WPS 3 and WPS 4 were licensed using a SETINIT / WPSKEY license file from the World Programming website. From version 4.4 onwards licensing is done by the Altair Units licensing system - either a file, an on-premise license daemon, or a connection to AltairOne. You may arrange this with your Altair Sales Account Manager well in advance.

Note 3: WPD file format version also changes so either conduct an acceptance test on a test system before committing, or back up all data files.

MINOR VERSIONS

WPS 4.1, 4.2, 4.3, 4.4, 5.23.1, 5.23.2, etc.

Note 4: Changing minor version does not require a new license.

Note 5: When users first use a new minor version, their Workspace folders are updated the first time they are used in the new version. Users may want to make a backup of their workspace folders - but workspace folders can be rebuilt in the case of a roll-back (by importing the contents to a re-created workspace folder).
