Beekeeping and Bees

I have an old bucket filled with soil which was used in years past as a stand-in planter for tomatoes on a balcony. Despite it not being particularly well sheltered from the elements, and now filled with whatever plants which have gone about seeding themselves since I stopped growing tomatoes, the pot has become a regular stop for little green sweat bees.

Long story short, I want to know about relocation of said planter (old plastic bucket for swimming pool chemicals filled with dirt, and now, miscellaneous plants), and how/when to do it. I like those little bees, and don't want to screw them over by dumping it out somewhere random, or especially during a time of year when said disruption would deprive them of shelter. Can someone offer advice on these points, please?
