I have an old SixBit version (v. 2.00.061).
If I opt in to the ebay Guaranteed Delivery (Handling time) - do I have to upgrade my SixBit from v.2 to v.3 - ?
And if I do decide to upgrade SixBit from v.2 to v.3 - will I have to re-build all my current item & inventory import/export maps, all shipping/payment presets, etc. in the new v. of SixBit - ?
Just trying to get an idea on the scope of work involved. Thank you for any info.
