Refreshing R/3 4.7 system from ECC 6.0 system

50 Views

HI Experts,

We recently upgraded the system from R/3 4.7 (BASIS release 620) to ECC 6.0 (BASIS release 701). For one of the test system, a cross version refresh was performed. (Sandbox system was in 4.7 and production system is ECC 6.0).

When the refresh was completed, we were not able to login in 000 client using any of the user ids including the standard ones. Seems like all the user ids were deleted in 000 client. Then we changed the sap* login parameter and restarted the system to reset the SAP* login. Later the user master was imported from production system to test system's 000 client.

Are there any special steps to be carried out to prevent the above said incident?

What are the special steps that needs to be taken care of in the scenario of 'cross version' refresh.

Please let me know your inputs on this.

Thank you.
