we are panning to upgrade our mongoose version from 5.12.0 to V8.4.1, our Mongo DB is V6.0.11 I understand that there are breaking changes related to callback and no more warning which we have taken care already. documentation suggests first go from 5x to 6x then 6x to 7x and 7x to 8x. which is very long and tedious as we have many services https://mongoosejs.com/docs/migrating_to_6.html#version-requirements https://mongoosejs.com/docs/migrating_to_7.html https://mongoosejs.com/docs/migrating_to_8.html await mongoose.createConnection(uri).asPromise(); I do not see anything related to schema update or issue with error If anyone has encountered issue during version upgrade? Should I go step by step as suggested in documentation?
