What is the proper way to migrate a site with an old version of ERPNext 14 to a newer version?

Simply updating the apps and migrating the site with bench commands has given me errors before

Hi @zeeeeeeeero,

Depending on the version and what type of customization is set in the older version that is most important.

If larger data and lots of customization are set in the custom app or base app then you have to check whether your customization is already done in the new version or not.

Lots of things… so …

I hope you understand.

Thank You!
