Hey, what's the best way to find the matching dependency versions for each angular versions?

[gouravpratapsingh]

Hii sir if i want to upgrade the angular from 9 to 13 do i have to update it 1 by 1 like, 10,11,12,13 or i can go for directly 13 ?
And also i had installed angular 8 in my machine but project is running on angular 9.0.4 ?
And another question is i have more than 20 3rd party package is installed in my project it is quite complex so is there way that it will be updated accordingly to angular 13 version ?

Where can we find which is stable version for depdencies

[sivakumarrockzz]

Thank you for the session, after upgrading all the required packages from angular 8 to angular 9, I got the below issues for npm run build:

BUILD ERROR
- error NG6002: Appears in the NgModule.imports of PaysafeCmplCommonsModule, but could not be resolved to an NgModule class.

This likely means that the library (primeng/table) which declares TableModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

592 export declare class TableModule {

how can we fix these issues? thanks in advance
