Restarting Adop From A Failed Session R12.2

When adop has failed what are the steps to restart the same patch with fewer number of workers:
For example to restart using fewer workers.
Is this correct?
$ adop phase=abort
$ adop phase=prepare
$ adop phase=apply patches=12345678 patchtop=/patch_directory
The above steps are not correct.
SOLUTION
This correct process can be found in the 12.2.x maintenance manual:
http://docs.oracle.com/cd/E26401_01/doc.122/e22954.pdf
Which documents the following commands:
 'adop phase=abort'
 'adop phase=cleanup cleanup_mode=full'
 'adop phase=fs_clone'
 'adop restart=yes'
restart the patching cycle by setting the environment again and running
 'adop phase=prepare'
Number of workers can be specified on the command line with the command:  adop phase=apply workers=8 patches=patch number patchtop=<your patch directory>
You can use  'adop -status'  to check the current status of the adop patching cycle.
