Chris,

 

I am also looking at “switching DBs”. ( In my case: MYSQL to Oracle.) So I tend to think this kind of thing happens from time to time with existing installs. Given the possible “move to the cloud” conditions I can also image the frequency increasing.

 

 

 

With the export/import option….

 

                How is point in time data handled?

                Would you leave that information behind?

 

If one was to set up a “grouper (Oracle) to grouper (PostGRES)” integration would that be the same idea, only in real time?

                (The architectural diagram describes it as an “XMPP/HTTPS” integration to “Another grouper”. )

                And again… How is point in time data handled?

Would be nice if you could create the tables in postgres with GSH.  Empty the tables completely, turn off constraints, and migrate the data from oracle to postgres, turn on constraints and good to go.

 

If you do export/import it is slow for large registries, might have some issues, and doesn’t do all the tables I believe, but should get you generally there and you can let us know if there are problems…

 

Thanks

Chris

Is there a “right” way to move Grouper 2.3.0 registry data from Oracle to PostGRES, or simply one database flavor to another?  Thanks.
