Issue Solution

XCP commands do not show the expected results when a junction path is used in the source or destination.

Use an SMB share path instead of a junction path when running XCP commands.

A traceback error might occur if the source, destination, or both is a junction with no directories and an online license is used in migration. If this occurs, the XCP command status is PASSED but the following error is returned at the end of the console output:

Error in atexit._run_exitfuncs:
Traceback (most recent call last):
  File "xcp\stats.py", line 214, in call_home
  File "xcp\histograms.py", line 387, in calculate_averages
ZeroDivisionError: division by zero

Use an offline license instead of an online license.

xcp copy with ACL migration

Error message logged in xcp.log file:
pywintypes.error: (1314, 'GetNamedSecurityInfo', 'A required privilege is not held by the client.')

An issue related to security descriptors because the migration user account only has the required privileges for XCP to retrieve owner, group, and DACL. It cannot retrieve SACL.
Add your migration user account to the "Manage Audit and Security Log” policy in your Active Directory.
