@sergiogonzalez I have tested all your changes and I think they are fine.
I have discovered that if we execute twice the UpgradeDocumentLibrary, all DLFileEntry objects are renamed, I have added an additional condition at query that avoid this.
I know that customer must not execute UpgradeDocumentLibrary more than one, but I think it is easy to solve and can help us in the future
