Hi,You need to remove the V4 SDK from the mobile app before installing
the V5 SDK. And If you are planning to upgrade to V5 SDK, I'd recommend
you check out
https://aep-sdks.gitbook.io/docs/resources/upgrading-to-aep and
https://aep-sdks.gitbook.io/docs/version-4-sdk-end-of-support-faq#frequently-asked-questions.
Let us know if you have any further questions. Best Regards,Yansong
