MyBB Community Forums

I am using older version of my BB - http://www.to-hawaii.com/forums/
I would like to update to the new one but before I have couple of questions.

1) My current site has user-friendly URLs using the Google SEO (1.1.6) plugin. Will the new version work with this plugin and keep the url stucture the same as now?
2) Is the most recent version of MyBB software responsive?

Thank you!

I'm positive it's compatible, if it isn't you can just update it in the plugin php.

Thanks!
Is the system responsive or does one have to install a separate responsive theme?

^ default MyBB system is not responsive. separate responsive theme needs to be installed.
