how are you guys connecting the 1.6.4 servers like crash landing and Bteam to a network of 1.7.10 servers. i am currently running a network of 1.7.10 and 1.9.2 servers and would like to add a couple 1.6.4 modpacks into my network. i am using bungeecord so the players can use a subdomain and the default port to connect. is there a special build of bungeecord that you are using or are you using 2 bungeecord proxys and a redis server.. Basically i want help in finding a build of bungeecord that will work with 1.6.4 through 1.9.2 servers.
You cant. You can go 1.6.x to 1.7.x, and 1.7.x to 1.8.x, maybe to 1.9.x But otherwise bukkit won't do it.
