Careful.
You old site probably runs encoding ISO-8859-1
Xoops 2.3.3 runs encoding UTF-8.
If you use special characters they will be converted to "funny signs"
If you are using local characters in UTF-8
- Take a backup of your existing site (files and db)
- Install 2.3.3 on your new site using ISO-8859 in the database
- Upgrade your old site to 2.3.3 (see release notes) - keep ISO-8859
- Change language/global.php to ISO-8859 instead of UTF-8 (the button of the file) (both sites)
- Backup your database of the old site and restore it on the new (phpMyAdmin export - import). (In between, check links in the db to the old site and replace them by the new site domain)
- Copy additional files as uploads, photo albums, themes, customisations, etc. from old to new.
