Hello all, I have no prior knowledge on ES and I'm trying to make an old code written for elasticsearch 6.5 to work on the 7.3 version.

So far I got the code updated and running however I can't understand why during re-index process I got this problem:

```auto
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Mapper for [title] conflicts with existing m
  apper:\n\tCannot update parameter [analyzer] from [autocomplete] to [default]"}],"type":"illegal_argument_exception
  ","reason":"Mapper for [title] conflicts with existing mapper:\n\tCannot update parameter [analyzer] from [autocomplete] to [default]"},"status":400}

```

There's nothing else indexed

```auto
curl http://localhost:9200/_aliases?pretty
{ }

```

Here's the definition for the fields

```auto
$params = [
            'index' => config('search.index').'-session-info-pages',
            'body' => [

That did not work for me. Even creating a whole new cluster with no indices the problem keeps occurring. As I'm not an expert on ES I'm afraid we will have to migrate the ES solution we have to use another company.
