<br>
my way: save all the data in the images to be sure and backup anyway the <br>
database, then try the migration tools. Only rescan if you can't find <br>
better way<br>

Never had any speed issues, some maintenance tools take time to finish. <br>
One big +150k collection plus several smaller ones.<br>

Do you write metadata to image files? If not, i think some metadata like <br>
tags and ratings will not be attached to the files if you start from <br>
scratch. Maybe it's then better to create the new collections and move <br>
the image files inside Digikam?<br>
<br>
