From the 12.0 UCCE Installation Guide:
The EDMT tool can also be used to migrate data from a Logger or HDS production server, to the one that has already been staged on version 12.0(1). These two-pronged upgrade steps are typically performed to reduce the downtime needed during cut-over to the new version. While the parallel 12.0(1) systems are staged and tested, the 11.0(x)/11.5(x)/11.6(x) production servers continue to process calls. On the day of the cut-over, the data in the 12.0(1) staged servers, can be updated or synchronized with that of the production server, by running the EDMT tool, for each of the Logger and HDS database.
is anyone done this step for any UCCE upgrade customer? need help.
