Good Morning,
I was hoping to get some technical assitance.

We currently have the following versions of Addagio products
AP 8.1A (070919)
AR 8.1A (070603)
AI 8.1A (070921)
GL 8.1A (070923)

I believe we need to update the Ledger to v9.0A, and with that comes a new version of the lanpack, also we need to upgrade the Recievables to 8.1A(070920).

We want to leave GL 8.1A functional and have it as a backup incase the accountant doesnt like 9.0A.

Are you able to recommend the correct way/order to upgrade these modules in?
Would it just basically involve installing ledger 9.0A to a brand new directory, and create a copy of the old database files for 9.0A to use and convert (leaving 8.1A where it is).

Any help would be greatly appreciated.
Regards,
