Database migration, from firebird to MySQL (MariaDB)

I'm migrating a delphi program to a PHP program. This Delphi program use a firebird 2.5 database and what I need to do is migrate this tables and information to SQL. It could be directly to a new database in MySQL or MariaDB or ti a SQL file with the create tables and inserts. Two important points: 1) The firebird database has blob types and usually this kind of fields could be a problem when migrating to MySQL. 2) All work MUST be done using an access like anydesk, Teamviewer or something like that and at specific hours (you can choose what hours) because database has sensitive information and can't be copied or moved. The OS is Windows, but could be changed to whatever you need.
