## Aliases migration
This project also include a script that allow one to migrate aliases from one instance of elasticsearch to another.
Exemple d'usage :
python tools/ --src-es https://<source-host>:443 --dst-es https://<destination-host>:443 --src-idx <src-index> --dst-idx <dst-index> --skip <ex: preprod>
Prefixes or suffixes to the alias with `--prepend` and `--append`.
It is possible to skip the copy of aliases including a particular string. The argument takes a list of strings: `--skip bar foo`.
La liste complète des arguments est visible en executant la commande suivante:
python tools/ --help
