What’s the effort to upgrade a Litium 6 Accelerator to Litium 7?
A lot of changes or a fairly straight forward upgrade?
Any “strange” problems to take into account?
Thanks,
Ola

It is quite a bit big upgrade since Globalization and Website module has changed.
You can read about the changes here:

The effort is also hard to tell since every customer solution is unik.
Best recommended approach would be to take a pure 7th accelerator and lift in customized code from your 6th version to be in sync with all new stuff buillt in v7.
