Unable to restore SAP backup due to br*tools version incompatibility

Hi Everyone...

Our SAP 4.7 production server is taking online backup to sapbackup folder.

for restoring the data to SAP 4.7 production-dr server, I copied from production\sapbackup folder to production-dr\sapbackup folder.

Further, I installed brtools 6.20 version successfully on production-dr and while restoring data in production-dr server using brrestore command. I was receiving an error as version incompatibility and also couldn't find br*tools 6.40 in SAP market place.

Can you please address the following :-

How can i restore data successfully from production to production-dr ?

Regards,

Sridhar.
