Sorry for my bad English.
I have a website on EE1. I want EE3. There is a big problem with convert database (old PHP and MySQL on the server and can't converted via EE2, and if i update the PHP and MySQL, my EE1 will not work).
That's what I came up with: put on a separate host of EE3 and just fill the database manually. Then update the PHP and MySQL on the main server, install EE3 and add there the backup of the newly database.
Is this a good idea? What should I know?
