Now I am going to convert VMDK to VHD .but I won't know how to convert this file and, I already tried using winimage and HyperV but, I need this VHD file for Azure Template Deployment and as per Azure recommendation azure only need Fixed VHD. Any suggestion please let me know.
Try out starwind v2v converter: https://www.starwindsoftware.com/converter
It supports practically all well known formats, performs fast and, as the saying goes, it just works.
You want to look into a tool called
qemu-img. It's sole purpose is converting between virtual hard disk image formats. It's command-line only, but it is reasonably fast, and very memory efficient. Documentation can be found here.
