Hello,
Please I would like to know if there are best practices to migrate a single search head instance with ITSI to a search head cluster.
I have a deployer and the ITSI running production search head should become part of the search head cluster, initially as the only existing member.
When everything will be up and running I will add other 2 servers.
I have read something about Enterprise Security migration related to bundle size limits, for example, but found few things About ITSI.
Thank you in advance and warm regards.
