Migrate MySQL spatial data to PostgreSQL(PostGIS)

We have a web system that uses MySQL spatial databases. We want to migrate from MySQL to PostgreSQL. Our database has geometry and point data types, 21 tables and its size is 1.6GB.

I’ve been looking for methods to do it. I have found some tools that help you to migrate. However most of them do not support spatial data like https://github.com/philipsoutham/py-mysql2pgsql.

I also took a look over https://gis.stackexchange.com/questions/104081/how-to-migrate-spatial-tables-from-mssql-to-postgis. I have just seen this post. I haven’t tried it yet, I don’t know if it could work for MySQL. Furthermore, I’d like to do it using DB managers reather than Qgis or ArcGis.
