Can I open an old database with a more recent version of EDT?

If you want to open a database saved in an older version of EDT, you may have to save it with an intermediate version. All older versions can be downloaded from the website, from page EDT > Downloads > Older versions.

Base saved with EDT 2019 to 2021: open the base directly with EDT 2022.
Base saved with EDT 2016 to 2018: install EDT 2019 in Evaluation mode to save the database, before opening it with EDT 2022.
Base saved with EDT 2013 to 2015: install EDT 2016 as an Evaluation to save the database, then repeat the operation with EDT 2019, before opening it with EDT 2022.
