Green deposit on the joints of copper water pipes

I was renovating my house and have to open up the ceiling. Once the ceiling was opened up I see that our copper water piping has some green deposit only on the joints. I was doing some research online and seem that the conclusion is mixed, some say not to concern while other think that it needs to be fixed.

There is one or two drops of water on the joint where there is green. Do I need to worry and replace the pipe with PEX and copper fittings ? If I were to do something now is the time as the ceiling is open up. I have attached a picture for reference.

Thank you everyone Name:  20161221_105800.jpg

A good joint does not leak so if you have a drop or two of water then the joint is leaking and should be repaired or replaced. I don't mess with repairing copper. I replace it with PEX. When the area is opened up it's a good time to replace it if you have the mind to do so.
