In SharePoint 2010, I have a BDC connection created by importing a BDC model file via central admin. However, the machine providing the web-service has changed and I need to update the BDC model's properties to reflect this. (In particular, the WSDL's URL has changed).
How can I do this? If I attempt to simply upload an updated .bdcm file I get the error:
Application definition import failed. The following error occurred: Cannot merge contents of LobSystem (External System) with Name 'TrainingService' as it appears to be different from a preexisting LobSystem in the current load context. Error was encountered at or just before Line: '13' and Position: '8'.
I am considering using Import-SPBusinessDataCatalogModel with the -Force parameter, but am worried that my existing lists based upon the external content type will break. Will this happen?
What is the correct approach for updating deployed BDC models?
