I want to note how to restore original condition of Acumatica if Unpublish project failed:

1. Restore the content of the App_Data\RollbackFilesfolder to the root folder of the website.

2. Clear the content of the CstPublishedfolder.

3. Delete the files placed in the Cachessubfolder of the App_Codewebsite folder.

4. Remove all external files deployed on the website
