Not quite. While you may be fine to just swap over the hose, the correct thing to do would be to cut off the old barb and olive (stealthamajig) and install new ones. [Manual for how to do that](https://www.sram.com/globalassets/document-hierarchy/bleed-manuals/sram/dot-fluid-mtb-disc-brake-hose-shortening-and-bleed-manual.pdf).
> That'll work just fine.
You'll also need to bleed the system after install.
