How can I upgrade my Strapi CMS from older v4.3.0 to new version v4.10.0
You should do this incrementally between version 4.3.0 through releases to 4.10.0
You can see releases here
Yes I have upgraded with latest one in npm package, but getting lot’s of issues.
Have you followed the migration steps for each release increment?
I follow this article Upgrade Strapi version | Strapi Documentation and done steps with npm only.
Please help me on this, unable to upgrade Strapi CMS
there are some important steps you want to do
This is to 4.3.0 to 4.3.6
Then from 4.3.6
to 4.3.8 then follow each one, some has more then just change package.json
