how to change Shared network path DAG

Hi,

I want to change the shared network path on an existing DAG (sql2012) but i cannot find how?

• To use the availability group wizard to synchronize data, you have to have a backup share that all the replicas can write to. You can specify the share by browsing to it or by entering its fully qualified universal naming convention (UNC) path name, \\Systemname\ShareName\Path\, in theSpecify a shared network location accessible by all replicas box.

Do i need to setup the DAG all over again?

Please help

Grtz. Hans
