Don’t get me wrong here, I am in love with strapi since an year so, and also have used in my personal and also freelance projects.
What I’m thinking is I’m definitely going to upgrade to v4 but what I’m thinking is, anyways the mongoose connector for v4 will be released after 6 months of the of v4 release right, so I’m thinking of upgrading to v4 after the release of mongoose connector.
Migration is not an issue, definitely strapi will provide some tools for that. But for me many sites are with mongodb.
