Question : Looking for 3rd party software that sync the file shares

My company wants to setup new branch in countryB. Currently in countryA, we got a medium-size network, with servers, workstations, firewall. I am thinking of establish a site-to-site vpn with country B network, extend the current MS Windows AD domain coverage to country b as well - for user credentials, log on. But, how about my file shares? I know Microsoft go Dfs, but how good is this implementation? Any 3rd party software that serve the same purpose of Dfs?

Answer : Looking for 3rd party software that sync the file shares

    Do you already have the UCL and CUWL?   7.1.5 and above for the new licensing.  I belive after you upgrade you just add the new license file and it will convert the dlu's to the new system so if you have 500 ip phones and 3000 dlu's I believe it would just switch back to 500 UCL/CUWL or how every many you bought.  
     If you have smartnet  I would call them up and ask to be 100% sure since its new and not a real requirement until 9.0 I dont know if many will be doing it. Though they do have a great deal on converting from DLU's to get people to switch over.
