Possibility of merging my two Apple-IDs?

Possibility to merge my two Apple-IDs w/o loss?

Unfortunately, when Apple abandoned the "me.com" cloud I have used in parallel 2 Apple-IDs. It worked on my different devices until the one individual one ID was introduced. Now again there is the trouble to shift to my "me.com" ID.

Cumbersome and costly new installation of all the iPhone apps, and the losses in this context were not only time-consuming, but also annoying and again and again kind of a pain in the neck.

I'm not really prepared to take that on with my MacBook again.

I would like you to let me know a consumer friendly "way out"....
