Hi All,
My client requirement is migration of jobs from 8.1 version to 11.3.
Taking all jobs export from 8.1 and directly importing into 11.3 version and compiling all jobs, it will work ? or need to migrate from 8.1 to 9.x , then again 9.x to 11.3?
please suggest best approach .
Thanks & Regards,
Sree.

You'll have to test
everything since functions change over time and bugs are smashed (that you may be unknowingly taking advantage of) but the short answer is 'yes'.

Adding to chulett, Yes, you can directly migrate to V11.3.
We moved from V8.7 to V11.3 recently, no major issues, just created packages using istool and deployed and recompiled on new box. But when you use istool -incdep option, certain user defined server routines will not catch up.

Yes, I second Craig's opinion that you will have to test everything (job execution, data etc) There have been changes to functions such as field() which we found to be "Fixed" in 8.5.3 which altered the functionality and was loading incorrect data in target and our jobs needed to be fixed. There are other fixes as well, so test thoroughly.
Also if you are using SAP Packs you will have to migrate from CPI-C stage to RFC connector etc.
