How to transfer a mesh from Blender 2.79 to 2.8 with respect to the scale?

Question

Blender

Started working in Blender 2.8. The measurement system here is metric by default. I chose centimeters. Then I needed a mesh (more precisely, a group of meshes highlighted in green) from an old work done in the 2.79 version. When added to the new version, the scale of the imported group is a hundred times larger than the size of the objects in the new work, although the metric system and centimeters are also set in the old work.
Yes, so far I have reduced the scale of the loaded group by 100 times (0.10) - but I can’t reset it to 100% using CTRL + A, because inside this group the meshes are duplicated with links and their change is blocked with a corresponding warning.
Question: how to add objects from works (in version 2.79) to works (version 2.8) with the same scale? So that a mountain is not added to the mouse (namely, this is how it looks)?
Thanks in advance.

Looks like a bug in Blender. He has data storage there and support for older versions is done pretty hard. The best advice I can give is to create an issue and hope it gets fixed, but for now, use the old version.
