Dear Gurus,
In our development system one of our colleague migrated the MM data sources from 3.x to 7.0. When we create transfer rules, at data source assignment I cannot see these data sources in the list. Please help me to convert back to BW3.x from BI7.0 for these data sources. Do we have this flexibility?
Thanks
Ram

Hi Ram,
Recovery of a DataSource 3.x
It is only possible to recover a DataSource 3.x if it was migrated with export. This allows the objects DataSource 3.x (R3TR ISFS), mapping
(R3TR ISMP), and transfer structure (R3TR ISTS) to recover the same
status as they had before the migration.
During the recovery the DataSource (R3TR RSDS) is deleted. The system
tries to retain the PSA. This is, however, not possible if the PSA was
initially generated for the DataSource because either there was no
active transfer structure for DataSource 3.x or it was loaded using
IDoc.
The dependent objects transformation (R3TR TRFN), Data transfer process
(R3TR DTPA), and InfoPackage (R3TR ISIP) are retained. If you want to
delete them, you must do this manually.

goto RSA5, re-install the 3.x datasource.
It is impossible to downgrade 7.0 datasource back to 3.5

Hi,
As per my understanding, Its always possible to migrate a data source from 3.x system to higher version, but the vice versa is not possible.
