I use both regularly, no big issue switching. Don’t worry.

Initially there was a difference for me, but now I can switch from one to another without a problem if I need to work on laptop keyboard for some reason.

Your brain is way more adaptable than you think. I go between 3 or 4 different keyboard layouts regularly and can use them all just fine. I think the secret is just to force yourself to recall locations from memory even if it takes a moment, only look up the layout if you are totally stuck. It’s also kinda fun to see how weird of a layout your brain can get used to. E.g. one-handed layouts, morse code, stenography etc.

It took me a month to get used to my Corne, mostly because I went split, and 40% (dependent on layers for everything). This was during the pandemic, so I was also WFH and didn’t need to use the laptop keyboard for a couple years.

When my company returned to office, and I started using the laptop occasionally, it took a couple hours to wake up my row-stagger muscle memory, but I’m able to switch between ergo and my laptop without issue.

You’ll be fine. Just be patient as your muscle memory adapts.

At first it was pretty hard, but I found that it became easier once I built up muscle memory for my Colemak-DH column stagger split keyboard. Suddenly switching between the split and my MacBook keyboard started working again.

no one wants to come back, as well as mastering the optimal layout, e.g. ColemakDH… Unless you have to - it depends on your practiced skills and muscle memory. I once heard a good comparison that it’s like driving two different cars - a good driver can switch cars and drive each one without any problems.

I had difficulty to begin with, but now I can switch between them with no issues.

I have three different kinds of keyboards. Regular, Alice and split ergo with columnar stagger. It always takes a little while to get back to speed when I switch boards. But I think that the layouts are different enough so that a distinct muscle memory forms for each one. I guess that the most important thing is that you should be fairly proficient with touch typing on a regular board before trying a different layout. If you are still in the phase of learning, I imagine that it gets really frustrating.
