The migration was very fast using a perl script to rename the packages:

```auto
#!/bin/bash

find . -type f \( -iname \*.scala -o -iname \*.sbt \) -exec perl -pi -e '
  undef $/;
  use Regexp::Common;
  $x= "(){"."}";
  $bp = "(?:$RE{balanced}{-parens=>$x})";
  $arg = "(?:[^()}{,]*$bp?)+";
  s/elasticsearch/opensearch/g;

' {} +

chcase -rd -x 's/elasticsearch/opensearch/g' .

```
