I'm currently migrating packages from v13 to v14, with the new back office, how do you call services like

editorService

from v13 to v14?

EditorService is not a thing in v14 anymore. You most likely want to consume a context to get the properties or methods you want to use

There is a sample in the docs here https://docs.umbraco.com/umbraco-cms/tutorials/creating-a-property-editor/integrating-context-with-a-property-editor If you are totally new to the new backoffice I would recommend the talk “Mounting your UI in New Backoffice, 2023” by Niels to get a better understanding of the concepts: There are a lot of info in the documentation (first link) and I’ve also curated some stuff here https://www.enkelmedia.se/blogg/2023/11/18/resources-for-umbraco-14-bellissima-new-backoffice
