The Support of LUM1 licensing technology will end on December 31st, 2013.
This technology has been replaced by DSLS2, which is already available in all V5 releases since V5R21, and in all V6 releases.
Dassault Systèmes is recommending customers and partners who currently use LUM as a licensing system for products under support, to migrate to the DSLS licensing system in 2013, if and when available.
You can get more detailed information in the document “REMINDER: LUM licensing technology End of Support” published on January 4th 2013 on your DS Support Portal (private access).
Customer Support Centers remain the primary focal point of customers/partners for support questions related to licensing.
