It worked for WordPress 6.2 but must do in parts

Well, I tried this plugin on my old site and it scanned but then would not convert. And then I tried again on the new site, the one that I already converted to a Gutenberg theme and it worked!! I am using WordPress 6.2. I think the best strategy is to only update 20 at a time on a page by page basis – through the Bulk action pulldown option to Convert where you check all listed and click Apply vs. Bulk Convert All button at top. I tried the Bulk Convert All and the minute I walked away from my computer and the screen went blank it had a server error but still managed to get half of them done.
