escallonia - )K to move it?

[Rowlers]

I'm hoping one of you green-fingered leadies will not be in the garden today but I have a feeling on such a nice day that won't be the case!
Got a rather large escallonia which we planted in the wrong place (we now realise) a couple of years ago.
Can we move it easily? Is this an alright time of year to do so?
We tried moving a choisya last year and it did not like it at all - was dead within a couple of months.
