HI Everybody

Just a general question as newish to Solidworks and Epdm world

Does everybody upgrade every year or every two years to some other time frame ?

The reason I asked is with the Local IT department as well as interstate IT department and Cad Users and 2 lots of Management, all taking a lot of time to do the upgrade from 2011 to 2012 ,  all I can see is a month of lost time every year, or it could be too many cooks.

Many thanks

Don
