Reset the PI Module Database based on elements in the synchronized AF Element

The Reset-PIAFLinkModuleDatabaseFromAF cmdlet will perform a "Reset MDB". This means the current contents of the PI Module Database will be deleted (exluding %OSI, %OSI_MCN and %OSI_ManagedPI) and recreated using the contents of the Root AF Element of the associated AF Database. The associated AF Server, AF Database, and AF Root Element can be found in the Module Database at: %OSI\MDB-AFMigrationData under the properties PISystem, AFDB, and RootElement, respectively.

The connection parameter specifies the connection to a PI Data Archive to use.

WARNING: This cmdlet should only be used if the potential ramifications are understood. Contact OSIsoft Technical Support if there are any questions about whether a "Reset MDB" is appropriate for a given situation.
