This is from 2.0.14 readme:
le="color: #000000"><?php Upgrading from any XOOPS version between 2.0.10 and 2.0.13.2 1. Copy the content of the htdocs/ folder except mainfile.php over your existing installation. 2. Delete the following folders and files: * class/smarty/core * class/smarty/plugins/resource.db.php 3. Empty the templates_c folder (except index.html) 4. Upload the upgrade folder to your site 5. Ensure the server can write to mainfile.php 6. Login using an administrator account 7. Access <your.site.url>/upgrade/ using your browser, and follow the instructions 8. Write-protect mainfile.php again 9. Remove the upgrade folder after use
So you should upgrade to 2.0.10
2.0.10 -> 2.0.14
2.0.14 -> 2.0.16
Be shure to make backups at any step.
