Migrate R2025a preferences to a new computer that is running R2025b

I am installing R2025b Matlab on a new computer. The new computer has no prior Matlab installations from which previous preference settings can be auto-imported. However, I have saved the prefdir from R2025a installations on past computers.

Question: Is there a way to get R2025b on the new computer to import my R2025a preferences using only the R2025a prefdir? I know one possible set of steps would be to,

(1) Install R2025a on the new computer.

(2) Drop the saved prefdir files into the fresh R2025a installation in (1).

(3) Delete the R2025b prefdir and restart R2025b.

However, I am wondering if there is a way that avoids the installation of R2025a in step (1). I don't really plan to use R2025a on this computer, and it seems cumbersome to install it solely for the purpose of migrating prefdir settings.

I also know that there are past threads on the topic of prefdir migration. However, these predate the massive desktop change that occurred in R2025, and I am uncertain whether they would apply to the newest Matlab versions.

Have you already tried the old method anyway? It would be interesting to see if it still works. It wouldn't make sense to me to have to install R2025a just to have the prefdir.

The "old method", as I understand that to be, is to copy certain .xml files (e.g. the ones responsible for keyboard shortcuts) from the old prefdir and drop them in the new one. But for R2025, I don't know anymore what files are responsible for what.

In particular, the location for keyboard shortcuts seems to have been moved. I have tried copying over the .xml files where things used to be held pre-2025, but that did not have complete success. My keyboard shortcuts remain at their defaults.

I haven't taken the plunge to move to R2025 yet, so this is just a guess...did you try moving over all the prefdir content regardless of trying to figure out what might be what?
