Yes, you should be able to open and use projects generated with a mix of classic and modern activities in newer versions of UiPath Studio. UiPath aims for maximum backward compatibility, ensuring that projects created with earlier versions can still be opened and executed in upcoming versions.
Projects created with a mix of classic and modern activities in UiPath Studio should generally be compatible with newer versions. However, it’s wise to keep backups and test in a non-production environment after upgrading, as there might be minor adjustments needed due to potential breaking changes or deprecated features.
