You are trying to migrate from WebSphere MQ V6 to V710 but you can not find the sample job CSQ45ATB in SCSQPROC to MIGRATE the DB2 table definitions from WebSphere MQ versions 6.0 (with the migration PTF installed on ALL queue managers in the DSG) to WebSphere MQ version 7
After correct installation of WebSphere MQ V710, no CSQ45ATB can be found in SCSQPROC
WebSphere MQ Version 710 does not have CSQ45ATB sample JCL in SCSQPROC, but it has another sample JCL named CSQ456TB to MIGRATE the DB2 table definitions from WebSphere MQ version 6.0 (with the migration PTF installed on ALL queue managers in the DSG) to WebSphere MQ version 7.1.
THIS SAMPLE CSQ456TB MUST ONLY BE USED BY CUSTOMERS MIGRATING
DIRECTLY FROM version 6.0 TO version 7.1.0
If migrating from version 7.0 then use the sample CSQ457TB.
If migrating from version 5.3.1 then use the sample CSQ455TB.
Resolving the problem
In WebSphere MQ v710, we have CSQ456TB instead of CSQ45ATB in v701
