Toast SEO & SmartCrawl SEO

I am considering downloading your plugin to shy away from Yoast SEO. My question is: if I download and activate SMartCrawl SEo while Yoast SEO is activated, will it cause issues or break the site? Should I deactivate Yoast prior to activating Smartcrawl? If I do deactivate Yoast, will I lose all the data I’ve created for it if I decide not to go with Smartcrawl?

Your plugin sounds amazing and I would love to try it out. Just hesitant of the unknown!

Thank you!
