need to downgrade CRMAPP software component 731 to 720

Hello Experts,

I have a requirement from my client to downgrade CRMAPP software component 731 to 720.

Current CRMAPP is at 731,our requirement is to bring CRMAPP to 720 version,

We are at EP 7.3 version, Aix 6.1 & DB 9.4

Here my question is how to bring it to 720 version as we don’t have SDM tool in EP 7.3 version, can it can be done with JSPM.

Please help out in telling the procedure to move CRMAPP 731 to 720

Regards,

Pavan
