I've inherited a legacy GIS, built up over some years in versions 2.x, that i'm now responsible to maintain. Being an almost complete n00b (did take a short course in QGIS a good few years ago, but still..), i could really use some advice about migration.
i've created a new QGIS instance in version 3.14, into which i am trying to bring all useful content from our old system: oodles of shapefiles, essentially, plus all those other files (each .shp file appears to bring with it a set of.shx, .dbf, .prj, qpj files, plus a .cpg file for each layer, it seems). This is a significant dataset- 14gb, >1000 files -and that is just base data, not counting Projects built on this data or Layouts used for presenting these projects in various ways. Some of this is cruft that i can happily do without, but still: i've got a lot of porting-over to do, without a clear idea of how best to do it. The one thing i'm clear about is: i want it all in a non-proprietary database (i.e. no more mess of .shp and related files) that is above all quick & easy to navigate & manage. It is a single-user system at this point, but i do aim to open it up to colleagues (off-LAN, i.e. via Internet) as soon as i've developed simple apps for them to use. No idea how long it'll take me to get there, so... Big question at this point is: What should be the new storage format for all this data? Having read a few related opinions on StackOverflow, i get the sense that GeoPackage will probably make for easiest migration (per this encouraging article <https://medium.com/@GispoFinland/learn-spatial-sql-and-master-geopackage-with-qgis-3-16b1e17f0291>, it's a simple matter of drag&drop -simple if you have just a few, i guess! [1]), and can easily support my needs in the short term, but then i wonder: How will i manage migration to PostGIS when i eventually put this system online with different users/ roles enabled? [1] Given that i need to pull in some hundreds of .shp files that are stored in a tree of many folders & subfolders, i also wonder: is there a simple way that i can ask QGIS to traverse a certain directory, pull in all the .shp files -each as its own .gpkg layer, i suppose? Any advice about managing this migration would be much appreciated!
