MIgrate from GTM ( Google Tag Manager) to Launch

Hello,

 We are planning to switch from GTM( Google Tag manager) to Launch. By that, all the tags, data Layer variables and triggers that we have created, we would like to move them and set them up in Launch. 

Is there any automated way to do that ? are they any migration tools available to do the same ?

Thanks,
