How do I upgrade existing ships?

[Андреја Костић]

So I have a ship design, and have built some ships with that design, which are docked at a shipyard.
Then, in the ship classes screen, I click on "UPGRADE" next to a design, and make changes, in such a way, that the VALID REFIT is set to true.
Afterwards, when I to the ship construction->refit docked ships screen, and select a ship docket at a shipyard, the VALID REFIT list is empty.

What am I missing here?

You can only upgrade them in minor ways. For example, I don't think you can upgrade rhem with an engine change. If compatible and the old fleet is flagged as obsolete, it should show up.

Well, the "VALID REFIT" which shows up when doing upgrades to ship designs has a tooltip which explains which types of upgrades are allowed, and if you make a change outside of the ones allowed by the list in the tooltip, the text changes to red "INVALID REFIT".
Since the refits were valid, I should be safe from having made changes which are too large.

Maybe it's a bug then? I found your question looking for this answer, did some tinkering and finally had a ship show up as being a valid refit in the ship dock.

I ran in a bug just now, where i cant refit my ships. I ordered a fleet of 8 to refit (identical ships) 3 went through and then it just stoped, no progress.
I canceled and tried again, nothing.

Yeah, I think it's a bug.
I've experimented quite a bit, in all cases with VALID REFITs, and as you mentioned, if it's very minor, sometimes, I'll be able to do the upgrade, and someitmes not.

Yeah sounds like a bug.
Also i would assume, when there is an "autodesign" button, they could also add an "auto valid retrofit" button as well. Could keep things less unnerving.

You seem to have a button to actually start upgrading a existing ship. Where can i find that? I have an old ship class and made a valid refit version of it (though the game gave it a new name). I also flagged the old class as old and have the ship docked on a wharf. But no matter where i look, i just cannot find any way to actually apply the upgrade. What am i missing?

Select the Ship menu. Go to Ship Construction, as if you were going to build a new ship. On the top left is a button "Refit Docked Ship". Use that, select the ship to be refit, and the design to refit it to.

Amazing - i never saw that button. Thanks!
