How long will eCM be supported for? considering WCM is out and there are no more enhancements being made to eCM?
Considering eSeries is still supported, so I would presume eCM would be supported for a while.
However, if it isn't then it would be wise to let the client know not to invest in any eCM customisations as they will have to be re-developed in the near future.
Also, it would be a good way to get clients to move to WCM.
