I have a few customers who are still running Sun Java System Directory Server Enterprise Edition 6.3.x. One of them called me this morning wanting to know when will 6.3.x support ends.
I think the following information is helpful.
Note: Support for Sun DSEE 6.3.x ends on Dec 2013 and there is no extended support. Any customer who wants to continue to use Sun DSEE has to migrate to 7.x.
