My colleague have installed license of SD 5.2 , and need to upgrade to ODSEE 11g .
So before technical activity, should them have to upgrade also the license or just used the old license ?
If you have a DSEE licence and a valid support contract, yes you can upgrade.
To be super accurate.
Assuming all required entries where purchased under a Sun DSEE license, not under only Sun DS.
If not sure please reach me out or reach your Oracle Sales Representative.
