We have a DEV environment with Managed metadata "Term Group" for our project e.g. TermGroupA. Another project uses a managed metadata "Term Group" e.g. TermGroupB on UAT environment.
We need to deploy our TermGroupA to UAT, we are planning to use Export-SPMetadataWebServicePartitionData and Import-SPMetadataWebServicePartitionData PowerShell script to do this (Note: We need to preserve the GUID, as these are attached to navigation)
Question: If we do Export and Import onto UAT - will this overwrite TermGroupB? or will this append our TermGroupA into existing Managed metadata database?
If it is going to overwrite and affect TermGroupB, is there any other portable option to move a "term group" across environments preserving the GUID?
No csv, as they don't preserve GUID and no third party tool please. Anything using PowerShell great. Thanks Guys!
