Do Upgraded Units Keep Their Promotions/Experience?

I haven't had the situation come up yet but I would like to know in case I'm going to take an elite unit and make it a green unit with only marginally better stats at considerable expense.
 
Units keep their promotions but it's expensive to upgrade. Some examples:

warrior to spearman = 85g
archer to longbowman = 100g
warrior to rifleman = almost 300g
catapult to cannon (or maybe artillery) = 800+g

(numbers might not be perfect but you get the idea)

In my first game I went almost all the way thru the tech tree and I don't recall seeing a wonder or tech that reduced upgrade costs (could've missed it though).
 
Ouch, you can buy a lot of production with that much gold.

As a side note last night I bought the Sistine Chapel to completion, I wasn't aware you could hurry it with cash.
 
I think the xp is limited to 10, judging from:

- <Define>
<DefineName>MAX_EXPERIENCE_AFTER_UPGRADE</DefineName>
<iDefineIntVal>10</iDefineIntVal>
</Define>

in the GlobalDefines.xml file.

The upgrade cost is a bit below that too, taking out the base amount makes the upgrade cost much more sane in my opinion.
 
It does appear that both the Art of war (a barracks in every city) and Leonardo's Workshop (upgrade costs ½) are both gone.

This makes upgrading my entire army in one turn highly unlikely.

Under one (just ONE) of the civics, you can hurry with money. I'm thinking Representation or Universal Suffrage? (Sorry, at work.)

Under another of the civics (Slavery?), you can hurry with pop points.

With all of the civics (???), you can hurry with chopping down forests.

Keep in mind, I don't have the game.

There's 17 after 10. But it's hard to get to.
 
I meant, if you upgrade, and you have more than 10 xp, it may drop it to a 10xp unit. Also, iirc i had a 22 xp unit at one point.

What happens to your promotions (do they all go away and then you reselect new ones)?
 
I have no idea, I've never really paid attention. Only found that line an hour or two before I posted that. I never got to upgrade very many units in my games anyway (except now that i have removed the base upgrade cost! muahahaha!). If I find out for sure before this post slips away completely I'll post the answer.
 
They keep all promotions. Its actually quite useful because you have access to skills the upgraded unit wouldn't normally have.

even if you have more promotions than 10 (if you have a unit that has 18 xp and four promotions..... does it drop to 10 xp and you keep all promotions (but not get any new ones until you get an additional 16 xp getting you to 26)?
 
Xeos is right about the 10exp limit.If you upgrade a unit, it will lose always all experience beyond 10 exp, but it will keep its promotions.

Implications of this:
- consider to promote only "green" units below 10 exp.Older veterans might be still useful and able to get high level promotion.If you upgrade them, the chance to pomote any further is reduced drastically, since you have to go the long way from 10 exp again.
- if you decide to upgrade an elite unit at all, make at least sure that the unit isn't about to be promoted soon.Upgrade it immediately after it has got a promotion (for example when at 17/17 and under no circumstances if the unit is at 16/17!), this way you will at least waste no points.
 
Also, note that upgrading isn't tied to barracks any more. You can upgrade anywhere in your territory. This is especially helpful if you're fighting close to home and discover the tech for a new unit. Retreat your army back a few spaces, spend a turn (and all your money) upgrading, and suddenly you have modernized units with promotions already at the battlefield.
 
It is limited to 10. I had a unit that was 23/26 and then I upgraded. The new unit dropped to 10/26 but kept all the promotions I had beforehand.
 
If you work your way back up with an upgraded unit that has the 17-point promotion, do you get to pick more promotions? Or do you have to wait until you've gained enough points to exceed your current level of promotions? (Sorry, 1am, not very clear.)
 
Example:

You have a unit with 16/17 exp, the unit wins an easy fight and you end up with 17/17.You pick the 4th promotion in the next turn and the experience treshold rises to 17/26.Now you decide to promote it.It keeps the four promotions, but exp drops to 10/26.For the ext promotion, you need 26/26, means 16 experience points.

So summarized you can say: Promotions are tied fix to the experience tresholds, the only thing which may drop or increase is the actual unit experience.
