2100610 - Downgrade from ASE 15.7 SP130 to ASE 15.5 hangs or is running extremely slow.

Symptom

  • Downgrade from ASE 15.7 SP130 to ASE 15.5 hangs or is running extremely slow.
     
  • A server process executing  sp_downgrade seems like hanging for hours at Step 999 at the very end of downgrade process.
    This is the end of the output:

1> sp_downgrade 'downgrade', @toversion='155', @override=1, @verbose=1
2> go
@fromversid = 15700' @fromversion = '15.7.0.0' @toversid = 155
Downgrade from 15.7.0.0 to 15.5.0.0 (command: 'downgrade')
...
