Migration from old CMS to WordPress 301 redirection rules?

I made modification of rules, now it is working fine.

#For post page URLs
RewriteRule ^(.*)-some-category-suffix(.*)-some-category-suffix(.*).jpg.html(.*)$ /category-url/$1$2$3.html [L,R=301]

#For post add-on page URLs
RewriteRule ^(.*)full-size/(.*)-some-category-suffix(.*)-some-category-suffix(.*).jpg-(.*)(.*).html$ /category-url/$1$2$3$4.html?-$5$6 [L,R=301]

#Category URLs
RewriteRule ^(.*)-some-category-suffix(.*)-some-category-suffix(.*)$ /category_url/$1$2$3 [L,R=301]
