now all server have the same version and it is almost complete now. what i did i actually copy the database on the panel which was updated and replaced those of the slave server with it, not i start to see replication happen, which is a good sign. only minor issue is the detail before i upgrade can be modify on the panel but not replicate unless i delete it on the panel and add it again , then only it can replicate to the slave ... where as it is contrast when i add totally new detail after update, it's get's replicate straight and work OK. is it how it should work or still i miss something
