Correcting a coordinate error on a base station in GIS

Hi, 

I realise this is a random one for this forum, but hopefully someone can help. I have a file of coordinates from a base and rover GPS setup which contains errors. I missed out a digit when entering the coordinates for the GPS base station (thereby putting the base in the wrong location). Because of this all the measurements taken with the mobile rover GPS were relative to the wrong original (base) position so are now in the wrong location. 

I presume there must be a way to work out a transformation to correct this and then apply to all the points from the Rover?

I know what the base station coordinates should have been AND I know what they were entered as. Only the longitude is wrong, the latitude is correct. i need the transformation results to be as accurate as possible as I am looking at small scale changes over time and comparing with existing datasets. I am sure I should be able to work this out in ARCPRO, but as yet have not thought of a suitable solution. 

I hope this makes sense to someone and they are able to help. 

Thank you
