Error: Can't complete action due to multiple items having same name

Hi ifaras 

Thanks for reaching out to Microsoft Fabric Community Forum.

Please consider following steps to resolve the issue :

1.  Before syncing, rename the conflicting items like the semantic model and SQL analytics endpoint locally in the git              repository. Make sure each item has a unique name.

Use Git commands to rename the conflicting files:

     git mv old_name.SemanticModel new_name.SemanticModel

     git mv old_name.SqlAnalyticsEndpoint new_name.SqlAnalyticsEndpoint

2. Update References: After renaming, update any references to these items in lakehouse, notebooks, scripts, or other        dependent files to reflect the new names.

3. Sync to New Workspace: Once all items have unique names and references are updated, try syncing the repository        to the new workspace again.

4. After syncing, verify that all items are correctly imported and test to ensure everything is working as expected.
