Welcome to the Q&A Forum

When you launched the new version of the site, did you set up the 301 Permanent Redirects so that all of the old pages are mapped/redirected to the most appropriate page on the new version of the site? It sounds so me like you might not have set up the 301 redirects properly. One thing you can do, though, is look at your Google Search Console crawl errors and pay attention to the most important ones--and fix those first.

Hi Ajay, Great question. First off, I think that both a video sitemap and the correct schema optimizations are extremely important in getting your videos to rank. Personally, I would start off with creating a video sitemap and then branch off into utilizing schema. This is just a matter of preference for me because I like to get the foundational elements done first. In terms of what tools you can use - I know of a few. If your site is in WordPress the Yoast Video SEO plugin has worked well for me in the past. If not, here are some great posts on Video Sitemaps and the best process for creating them. https://www.distilled.net/blog/video/creating-video-sitemaps-for-each-video-hosting-platform/ https://moz.com/blog/video-sitemap-guide-for-vimeo-and-youtube Hope that helps!
