The Azure DevOps extension for PowerOn Pipelines has two tasks ValidatePowerOn and SynchronizeDirectory. For GitHub, these are split into two individual actions and can referenced as such in your GitHub repository designated for Symitar.
This GitHub action will synchronize your PowerOn files, DataFiles, LetterFiles, or HelpFiles in a very configurable way. Choose to pull remote files, push local ones, or mirror the Symitar directory with yours. To learn more about it, check it out here: https://github.com/libum-llc/synchronize-symitar-action
