Upgrade from Tourney to Alivio RD with Stem Shifters?

Working on a beginner bike which came with stem shifters. The stem shiftera are Shimano and indexed with 7 speeds. Is it worth swapping out the rear derailleur for an alivio 9 speed derailleur which I understand also works with 7-speed index? Will the Improvement be worth the effort?

If the current Tourney derailleur shifts adequately the difference from switching to Alivio may not be perceptible. New cables and housings will often make a significant improvement in shifting, however.

that's precisely what I want to know thank you. I will be using the 9 speed alivio RD effectively as a 7-speed rear derailleur and I wanted to know whether it would shift better than the tourney 7 speed rear derailleur

A new Alivio, which is a couple steps above Tourney, should work better than a used Tourney once adjusted correctly.
""Worth the effort" depends on your level of expertise to accomplish it. IMHO there isn't a lot of effort required to replace and adjust a RD.
It also depends on the satisfaction or dissatisfaction you have with your current set up as well as the condition of the rest of the system (shifters/cables/chain/rear cogs)

Like dsbrantjr mentioned, new cables, housings, and a good cleaning of everything will give you an improvement.

If properly set up, a Tourney should shift 7 speed "good enough".
Personally, I only go 1 speed "skinnier" on DER's. As the # speeds goes up, the cages get narrower which can result in premature chain rub with your old, fat chain.
I would give the Tourney a bit of love first. Maybe you'll find it to be totally adequate?

How does your Tourney derailleur attach to your bike? Will an Alivio derailleur even fit?

Via hanger of course. Yes both fit.

Have you done it yet? And if so, has the shifting improved?
