What is the best way to migrate less files from v4 to V5

[AmrAhmedA]

I'm currently looking for document dedicated for the less migration from v4 to v5.
I understand that you have discarded less entirely in your v5.
One of the biggest challenges that you guys didn't yet address in details and how to handle them efficiently is migration from less files to antd cssinjs.

If there is huge code base being dependent on less files with the global variables in it. and out of sudden you abandoned less. what is the best way to handle this?
I assume that migration from less to cssinjs is big change and would require decent amount of time. there should be migration manual dedicated entirely for less to cssinjs.

we are working on this. You can find some example in this link. https://ant-design.github.io/antd-style/guide/migrate-less-codemod
But there's Chinese only by now.(You can use translator to read it).And this application level cssinjs solution will release on 2023.02 later or March maybe.

you should await a bit more IMHO
last remaining missing design tokens and classNames are in feature branch and should be in next weekly release

actually it should be in next monthly version 5.9.0, in a few days

hey all. I am also trying to migrate to v5 but the less tokens present here:

const mapV5Token = defaultAlgorithm(defaultSeed);
const v5Vars = convertLegacyToken(mapV5Token);
const mapV4Token = theme.getDesignToken(defaultTheme);
const v4Vars = convertLegacyToken(mapV4Token);

do not contain the prefix-cls less variables.

what can I do in this case?

I looked at that codemode but it forces me to install yet another thing and I just want ant less to still work as before

[dagadbm]

So I went to old ant v4 code and found the prefix-cls names and just replaced them directly on my code. just in case someone stumbles upon it. easiest solution I could think of.
