Hi,
Acymailing v5 and v8 can co-existence on the same site. Both versions have their own separate database tables, menu items, and modules.
When you install v8, you have the option to migrate your data from v5 to v8. The migration process takes place in the v8 database tables, leaving your v5 data untouched. However, please note that you can only link your license to one version at a time. You have the flexibility to unlink and link your license between versions as needed.
In v8, migrated templates are referred to as HTML templates. These templates can be edited using the website editor, which is JCE in your case. If you wish to continue using this editor, you must work with templates. When creating a new template, you can choose to use the website editor or the new drag & drop editor. If you start a new email without selecting a template, you will be directed to the drag & drop editor. However, if you start a new email using an HTML template, you will be presented with the website editor.
I suggest installing v8 and migrating your data (v5 will continue to function without interruption) to familiarize yourself with v8 and its features. Once you feel confident, you can proceed with the migration process again to ensure that your v8 version has the latest copy of your v5 data. After that, unlink your license from v5 and link it to v8. Finally, you will need to recreate your frontend menu items and modules using their equivalent v8 versions. By following these steps, your migration will be successfully completed.
Please keep in mind that while we still support the use of the website editor, the future of Acymailing lies with the drag & drop editor.
