Hello,
I am upgrading Mediawiki from 1.28 to 1.35
I have an issue using the search fonctionality (i cant found page ) and i have message (An error occurred while searching: We were unable to complete your search due to a temporary problem. Please retry later.)
I am using CirrusSearch V1.35 and elastica V 1.35 extensions and i have installed elasticseach V6.5.4
In the upgrading process should i also migrate/upgrade data and index from old elasticserach (2.3.3) and restore it to the new version of elasticsearch or i just install elasticseach 6.5.4 with new settings (new cluster ..) ?
Thanks very much
