Need Help with V1 to V2 migration

Hello! I am a beginner at using PlayCanvas. I have been following a tutorial and making a game through V1 and recently found out about the migration. Is there a way for me to edit my game still using the V1 version? Is the V2 that different from what is taught for V1? I am worried I might have a hard time using the new version with my game since I do not know that much about PlayCanvas. Thanks in advance!
