Query is :- can this be upgraded to 4.0.0 M6 by following the steps at "https://confluence-eng-sjc1.cisco.com/conf/display/NSOCoreFP/TSDN+4.0.0+<del><ins>M6</ins>+</del>+CFP+Upgrade+from+3.0+to+4.0" ?  And we should have all the 300K VPN services intact with no issue i.e Should be able to use them even after upgrade. NSO - 172.20.63.190 (cnctest/Ovatest123@)Could you please check and confirm on this upgrade support.Thanks,Sreedhar.
