Comment 3 Mike Fiedler 2018-02-05 19:49:49 UTC 
Tested the following clients against a 3.6.173.0.86 server:

3.6.173.0.101
3.7.27
3.8.32
3.9.0-0.36.0

For 1000 projects oc adm migrate authorization time was reduced from 14 minutes (pre-fix client - 3.6.173.0.86) to 6-7 seconds.   The 14 minutes is inline with the estimate above of 5 hours for 20K projects

For 20000 projects, migration time with the fix was ~ 2m 20s for all versions of the fixed client. 

This can be marked VERIFIED once a functional team regression of the command is performed.
