How To Upgrade The Theme?

[numan1980]

Hello there!

We have purchased themes multiple times for our projects, but now we are facing an issue. Our customers are requesting an upgrade, but we are struggling because our template is quite old.

We are using the Ultima template, version 8.0.0, which is based on Angular 8. When we initially developed the project, we simply ran "npm install" and customized it to fit our needs.

Now, when I update the package.json (e.g., "primeng": "^19.0.5", "@angular/core": "19.0.5", etc.), the project runs, but the CSS files and pages are completely messed up.

Is there an easy way to upgrade the template? Maybe some tools? Otherwise, we might have to rebuild the entire project from scratch since, as I mentioned, it's a total mess!
