I just moved to 2024. I read the manual on updating the scenery but still a little confuse. LNM is on a network pc. With 2020 I would move a copy of the sqlite file to lnm on the network pc. I made a copy of 2024 scenery. Do I move the whole little_navmap_db or just the sqlite file. The load scenery lib is gray out in LNM.

You should copy "little_navmap_msfs24.sqlite" for MSFS 2024 and maybe "little_navmap_navigraph.sqlite" if you have a Navigraph subscription.
All the same with remote PCs as with MSFS 2020 except the different file name.

The folder little_navmap_db contains more databases for userpoints, user airspaces and more.

Thanks.
