I've looked for days and finally I've found some people talking about DVDFab DVD to Blu-ray Converter and download to try some time. It works quite nice. So I paid for it. I love this app very much!

DVDFab DVD to Blu-ray Converter acts not only as a professional DVD to Blu-ray converter software, but also as a DVD backup software, which can merge content from many DVDs to a Blu-ray disc/ISO/folder without the hassle of swapping discs when watching DVD movies, or backing up many episodes of a series or DVDs to HDD in just one Blu-ray.
Load DVDFab DVD to Blu-ray Converter, and load the source
Double click DVDFab 10, and opt for Copy from the option bar when it runs, then click the copy mode switcher to choose To Blu-ray. Insert the DVD discs you want to convert to Blu-ray into the optical drive, or navigate it through the Add buttons on the main UI. When the sources are ISO files or folders, you can just simply drag and drop them into the main UI for loading.
Personalize the output Blu-ray
Select the titles, audio tracks and subtitles you want to copy after source loading, and choose the output media size and the output path, and then click the Next button to continue.
Drag the titles you have chosen to rearrange the playback position in case you need, and click the Next button to continue.
Choose one playback menu you like from the templates provided, or No Menu if you don't need one, and click the Next button to continue.
Name the output Blu-ray at the Volume Label and choose the playback mode you need.
Start to convert DVD to Blu-ray
Click the Start button, DVDFab will immediately begin converting DVD to Blu-ray, and provide you the detailed progress info during the process. You can cancel the task anytime you don't want to continue during the process, and you can also set your PC to automatically shut down, exit program, hibernate or do nothing when the task is done.
