I have indices that have "name.exact" or "album.album". I want to ugrade 1.7 to 2.4. I took snapsot and when I restore it : unable to upgrade the mappings for the index [metadatav4], reason: [Field name [album.album] cannot contain '.'. I should restore all the fields of all indices. How can I achieve this?
May be a split brain issue?
something went wrong
What exactly?
