I need to move a whole directory structure over an existent directory structure which can be probably 90% similar. The files needed to be moved might have identical name correspondents in the directory target. It would be needed to be made a comparison of the same named files and to rename the one older with the date-name appended to the file name.
So: if source\dir1\file1 is older than target\dir1\file1 then rename source\dir1\file1 to source\dir1\file1_mod-date-time and move to target\dir1
Similarly: if source\dir1\file1 is newer than target\dir1\file1 then rename target\dir1\file1 to target\dir1\file1_mod-date-time and move source\dir1\file1 to target\dir1\
If there is no similar file in destination folder just move it there - and create a new sub-directory if not existent.
I am novice at Powershell and I tried pieces of this to make it work, but no success.
Any help would be VERY appreciated.
Thank you.
