right 👍 in the same structure, a complete data folder (iGO_xxx) can be transferred from a device to that, i.e. 100% 1to1
Otherwise, it is always advisable to have the save folder rewritten.

It is also critical to copy Userdata/poi/ with all files, including index files, to another device! Always transfer only the *.KML! otherwise there may be problems with indexing, consequently user POI will not be recorded and/or displayed.
