My department is in the process of migrating data to a more consolidated structured series of GDB's. We are working toward something along the lines of of having 5 different GDB's and placing all of our data in those. For example instead of having multiple one-off GDB's for leasehold we will have it all in one GDB. The issue would be that we have leases in 5 different projection zones (NAD 27 State Plane) thus creating the need to have our GDB in one of those projection zones or having the GDB not have a projection. Then we would just project the MXD's that the data is used in. I am trying to avoid moving a lot of data and then later down the road finding issues with this approach. Are there any issues or a perhaps a better way to approach this issue?
