Hello,
we have a cluster environment:
- Search Head Cluster (3 nodes)
- Indexers Cluster (4 sites) 10 nodes each
actually is still with version 7.3.9 based on CentOS.
We have to migrate the OS to Suse linux and at the same time upgrade to Splunk 8.2.6 , we want to prepare a parallel environment with the same number of nodes where to install the latest Splunk version.
We also would like to use this new environment to migrate and fix the apps to be compatible with python, xml and jquery then start the env in production.
We are struggling to find a way to migrate the indexes buckets (db_* and rb_*) and kvstore from old to new environment with less downtime and loss data, if it is possible what about the the GUID in buckets name.
Thank you.
