3147930 - How to speed-up migration from one platform to another - SAP ASE

Symptom

Trying to move from Solaris to Linux and process is taking weeks - would like to find a way to decrease that time frame.

  1. Currently, the process we are using is dump from Solaris
  2. Load to Linux, this is taking hours to just load the database. (2k server 6Tb database)
  3. Running the sp_post_xpload - is taking weeks to complete.  
  4. Tuning has been done to try and increase performance. 
    1.   The  “max utility parallel degree” is calculated at 2 times the number of partitions + 1 producer
      Therefore, if the “max utility parallel degree“ is set to 255 (the max value allowed)  it will be able to consume what it needs to the maximum.
    2. ASE uses sort buffers for sorts used by operations including create index.  
      This equation estimates the amount of procedure cache required (in bytes):  (<Number of sort buffers>) X (<rows per page>) X 100  (currently set to number of sort buffers = 32767

What else can be done to speed up this process?
