Administration - Installation - Core: migration 5.4 PHP 7.3 to 5.4 PHP7.2

Hi,
I first installed a docker sturai/ilias 5.4 php 7.3 but because I get a lot of error I installed a new docker image Ilias 5.4 with PHP7.2.

I'm now trying to migrate the datas but I get some problems :
- I copied external data directory
- I copied internal data directory  (web directory)

Same config and Database, but after login, error.php, but I get a message from the browser that page cannot be shown because of wrong redirect.

Any help appreciated.

Regards
