Making an upgrade without ElasticSearch

Hi guys,

I'm trying to upgrade a Sugar instance from 7.5 to 7.7 but for the moment ElasticSearch service isn't available on our server. This cause that the upgrade can't execute as expected. The message "Couldn't connect to host. Elasticsearch down?" repeats every time I tried to did it.

Is there any way to make an upgrade if ElasticSearch service isn't running properly?
