I already open a TAC case but maybe somebody here has seen this before .

Thanks in advance

Is your CLI session getting stale?  Try to refresh current directory:

# cd /tmp

# cd /root/svn/mercury

(don't really need cd /tmp, but that's just precaution to make sure you exit current directory before returning to it)

Then try the start_amp_upgrade command again.

The reason this might work is because during the upgrade, the /root/svn/mercury directory is moved to mercury_old, while a new mercury folder is being built.  At failure, the AMP tries to back out by removing the new mercury and putting mercury_old back into the mercury directory.

If this doesn't work, please open a support case to track.
