How can I migrate data from stand-alone indexers into a cluster under 6.6.2?



I have 10 servers that are end of life. So I am replacing them with 10 new ones. I stood the new ones up as an index cluster and things went well. I sorta assumed I could copy the data from each indexer, reboot and the cluster woudl pick it up. This does not seem to be the case as I am getting the message below.

Can someone point me to the correct procedure here?

It looks like your indexers cant communicate with the cluster master.. You need to update your server.conf on the search peers to point to your master

If you did this already, then it could also be a bad pass4symm key value


master_uri =
mode = slave
pass4SymmKey = whatever
