Hi again Moses,
The function itself should not affect anything, but its never a good idea
to do these things directly on a production database without extensive
testing.

Note that this function WILL remove data depending on whether its
overlapping. So, if you have two data values for the same period/data
element/cat option combo/attribute option combo , one of these is going to
be lost or at least affected in some way depending on the merge strategy
you chose. If there is no overlapping data, then there should not be any
data lost, but like I said, be sure you test it very carefully before doing
this on a live system.

Regards,
Jason
