About Hotfix Maintenance
If you are sent a patch to address a specific urgent issue, it is referred to as a hotfix patch. Hotfix patches have been quickly created by our engineering group for timeliness and are not for general use.
Hotfix patches are not automatically carried over through export and import processes during an upgrade or migration. They need to be reapplied if you migrate to another instance that is the same version. Hotfixes are also built for specific versions of TDV, so they should not be used for later versions of TDV than the version for which they were built.
For hotfixes, run the update process for TDV and Business Directory.
