Guide for keeping LDP software current for LDP Production Environments
1. How to Get Support for running the LDP software
· use the LDP documentation (admin and user guides) posted on GitHub at https://github.com/library-data-platform/ldp/tree/main/doc
· post questions to the #devops channel on the Metadb/LDP Slack
...
3. Consider What Versions of the LDP Components to install
· See the Library Data Platform section of the FOLIO documentation, which includes a recommendation matrix for the 3 components by FOLIO release
· In general, install the latest production release for each component of the LDP software. The LDP and ldpmarc software components do not have a dependency on FOLIO (flower release) software versions, but the folio-analytics software component is intended to be used with specific FOLIO releases - https://github.com/folio-org/folio-analytics#releases
· It is safer to install only releases (tags) and to read the release notes and make adjustments to your environment if necessary
· Do not install beta versions in production environments, as they need to be tested before they are used in production

Time Zones
Both the FOLIO Application database and the LDP Test and LDP Production reporting databases are set to the UTC timezone.
Metadata, such as created time for instances, would be in the same timezone on both databases as well. The time reflected in the UI is a local setting.
