In Working with UDAs and adding them to a SharePoint Machine, what happens if you publish them multiple times?

Question asked by sonisick on Jul 7, 2016

For the workflows to work without manual tweaking, I need to publish the UDA file not nwf file. 

 

Also for installations to different environment (Development, Test, Production), the PowerShell scripts may have to be run more than once as updates occur.

 

I know the Guid a UDA uses is unique.  What happens if I republish the UDA--with or without changes to the actual UDA. Will this cause problems? 

 

If this will cause problems, 1) How do I update a UDA not changing the Guid  --Do I need to delete/uninstall the UDA first? How do I detect it is already there programmatically.

 

( Anyone have any PowerShell Code)
