Hello @Lim_Leng
Only option for you is to upgrade the Studio to the latest version we have today. However, as you said, there can be version issues as you said. But, these can be addressed through the dependencies and downgrading them…
So, have a note on the dependencies and their versions you had for each workflow on Old studio. Once you upgrade the studio to latest version, go to dependecy manager and downgrade those packages to older version. This will help with backward compatibility…
Though this is available, I do recommend to you upgrade those workflows to the latest package versions as well slowly…
