As far as I know, you can't transfer your video from one channel to the other. YouTube has given options to download your own videos from the channel and can re-upload your downloaded video to your new channel. Once the videos are uploaded into your new channel, delete the original video which you have in your first channel. Then the count, likes and statistics of the video will be continued with your new channel.
There is one method in which you can transfer your video without downloading and re-uploading. That is, first setting your video as Private. Once it is done, add your new channel to it. The viewers can view your videos from there. This could be simpler than anything else. Now change the video's license which is going to be transferred. It may allow viewers to remix your video. Now change into your second account. There you can proceed with the remix button on the video. This will copy the video which you tried to copy originally. Then the video will come in to your new channel. Once this process is completed, don't forget to delete your existing video in the old channel.
