SAS^® data sets that are migrated from a 32-bit to a 64-bit platform might take longer to process if PROC MIGRATE is used to migrate the data sets.

To circumvent the issue, do one of the following:

• Run the PROC MIGRATE step using the BUFSIZE= option, specifying a 64K increment:

  proc migrate in=in out=out bufsize=128K; 
  run;
  

• Use PROC COPY to recreate the data sets natively on the 64-bit platform:

  proc copy in=in out=out noclone;
  run;
  

Beginning in the third maintenance release of SAS^® 9.4 (TS1M3), the default bufsize is the buffer page size of the current session.

For information about performance, see Performance Considerations under Windows in the SAS^® 9.4 Companion for Windows.
