Hi Everyone,

Our use case is that we have a 6.4 cluster which has recently passed over EOL.

We would like to move to a new cluster which is running 7.6.

We have looked at many different options for migrating; one of the requirements is that we obfuscate the data before moving it to a different cluster.

Could anyone suggest a valid approach? I've read that streaming the data from the existing cluster via logstash and into the new cluster.

Any advice would be appreciated.

Thanks, Lee
