LabKey provides clients with three types of regular releases that are suitable for production use:
LabKey also creates nightly snapshot builds primarily for developer use:
We strongly recommend that every production deployment stays updated with the most recent maintenance or monthly release. Upgrading regularly ensures that you are operating with all the latest security, reliability, and performance fixes, and provides access to the latest set of LabKey capabilities. LabKey Server contains a reliable, automated system that ensures a straightforward upgrade process.
Recognizing that some organizations can't upgrade immediately after every LabKey ESR or monthly, upgrades can be skipped for a full year (or longer in some cases):
This upgrade policy provides flexibility for LabKey clients and the product team. Having a window of support for upgrade scenarios allows us to retire old migration code, streamline SQL scripts, and focus testing on the most common upgrade scenarios.
The table below shows the upgrade scenarios supported by past and upcoming releases:
