We have been using the standard VPN client and concnetrator for sevaral years. We now have several users that have purchased new PCs and with them the 64 bit OS. From what I have seen so far Any Connect is the only option for the 64 bit OS but it is not supported by the concentrators. I was wondering what options we can offer until the concentrators are replaced to support this user base? What are others doing to support the older user base while trying to migrate for the newer user base? I am not sure how soon we will be able to replace the Concentrators we use today.
