When the K2 Server is installed, a high-trust certificate is generated and stored in the K2 database. This certificate is unique to that K2 environment. When the K2 for SharePoint App is installed, the SharePoint environment reads this certificate from the K2 environment. When there are multiple K2 environments (for example a Production environment and a Development environment) which connect to the same SharePoint server, only the most recently registered K2 for SharePoint App will work because of the unique certificate that was read from that K2 environment's database. This article describes how to use tooling to copy the high-trust certificate between K2 environments so that both K2 environments can work against the same SharePoint server.
