Copying catalogue and original raws from laptop to master

Before I do anything daft I'd very much value comments on what I'm planning to do. I have recently taken a new PC laptop along to a 6-day workshop abroad during which I took several thousand raw images on two camera bodies.

Parallelling my usual workflow at home, I copied all the raws from the cards in to a meaningful folder structure on the laptop, and then went through and have selected and copied a couple of hundred keeper images to a couple of new 'keeper' folders (one folder per camera body).

While away I imported all the keepers in to C1 on the laptop and worked on a couple of dozen of the keeper images (both in C1 and varied Nik programmes). All the resulting TIFFs have been imported in to the C1 catalogue on the laptop.

Now I'm home again, what I want to do is:

1. Copy all my keepers in to my master catalogue on my PC desktop.
2. Retain my C1 work that was done on the laptop on some of those images, but review the resulting TIFFs on the desktop and make further edits.
3. Work on the other keeper images that I didn't edit while away.

Having RTFM'ed, I think what I should do is export the catalogue (with the images included within it) on the laptop, then import that file in to my master catalogue on the desktop.

Is that a reasonable way forward?

I'll be taking the laptop on similar trips in the future and doing the same thing; are there any gotchas that I need to be aware of? For example, I suspect it would be best if I kept a separate catalogue per trip on the laptop, and merged this each time I returned to the master on the PC desktop - yes?

[I'm not currently bothered about all the non-keeper raws on the laptop disk, although I'll probably back them up to my local raid drive]

Many thanks for any comments and advice.

All the best,
Mark
