Hello; my computer has crashed so I'm going to install everything again.
I used to have 5.3 version og GRASS (for me very good job along with postgres
and R) and now I've seen that the las is 6.0.0. But I've downloaded it and
the source is very small.
Please, what should I install to have a complete upgraded & stable version?
First 5.4 and then 6.0?
Would all my old grass53 databases work directly with this?
Thank you for the help and best wishes,
Javier

No, you just need to install 6.0 (or both).
Both versions stand on their own now.

Pretty much. Vector and site maps need to be updated to the new format.
A v.convert.all module is included.
Raster maps will be the same, with additional 3D ability.
Be aware postgres interface has changed (vastly improved, different) and
GRASS 6 / R interface is still under active development. Also be aware
that GRASS 6 modifies the mapset's region settings to allow 3D support.
This causes trouble when you want to go back to using 5.4 after you have
been using 6.0, but is easily fixed. Hopefully one day there will be a
5.4.1 release which ignores the new 3D settings and issues an error or
warning when a raster map with 3D data is accessed.

Yes, we reduced it significantly: from 1.x million lines of codes to
something aroung 500000 lines. 
There was a lot of unused stuff in 5.x.
We also changed from static to shared libraries which significantly
reduces the size of the binary package.

No, only 6.0. It is complete.

- raster data: yes
- sites data: sites are managed as vector points now.
use v.in.sites or v.in.sites.all (the latter to convert all
sites maps in a mapset in one step)
- vector data: enhanced format with DBMS integration
use v.convert or v.convert.all (the latter to convert all
vector maps in a mapset in one step)
Hope this helps
