Migration from 14.0 to 15.1 SP06

Hi,
We are planning to migrate to MII15.1 SP06 from 14.0 SP08 due to slowness and screen freezing of applets with Java 1.8. We are using iGrid, iCommand and iBrowser. For iGrid, i5Grid can be replaced. Whether do any equal component for iCommand and iBrowser available in MII 15.1? Whether does SAP provide any tool to migrate MII applet to UI5 component in HTML / IRPT files?

Thanks,
Raman N
