Deployment Architecture

Is it possible to merge two search clusters?

Explorer

We have 2 separate search clusters fed by the same index cluster.
The reason to have two search clusters was to host 2 sets of apps/add-ons that serve 2 different functional groups.

Now we are thinking about making one big search group. We'd like to migrate all apps/add-ons, reports, dashboards etc. from 2 old clusters to the new one. Both old clusters use the same LDAP server.

Anybody with similar experience?

There is no magic process to merge 2 SH, or 2 SHC.
You will have to do some manual merging of apps/configs/users/profiles/dashboard/datamodels..
If all your apps are different, it's probably easier, but if the same app existed on the 2 locations, you may have to go down to the /local and /lookups folders and selectively merge the conf files (and resolve dupes stanza)

For datamodels, if you had 2 identical ones with acceleration, you can only keep one of them.

I have scripts such as transferknowledgeobjects.py in https://github.com/gjanders/Splunk which might help move knowledge objects around but merging 2 search head (or clusters) will still take quite a bit of work...

We have a similar setup. One SHC for Security, one for everyone else. If you have Enterprise Security or ITSI, I suggest you keep them separate.

The things you might run into is Knowledge Objects like lookups with the same name.
