Similar spec system -- can't say I've noticed this with a couple of reasonably largeish apps
I've migrated to XE2 from D2010.

They did a pretty good job of making it seamless, especially in terms of standard stuff like
component properties, common classes and such - little or no code change or adaptation
required. Where I've encountered gotchas is in migrating or merging bits of older systems
e.g.:

* code which uses strings as buffers in some fashion -- more common in our real-life apps
than I'd have liked

*  code which outputs text data which must be read/processed by older systems, e.g. D7
apps. You definitely have to do some backwards-compatibility work there, to force Ansistring
instead of Unicode output. But not hard once you've isolated all the places it matters.

There are good Unicode primers out there on the interwebs, and also some reasonable
discussion on how Delphi is doing it. But I'd have to say I've not learned it very well as yet,
and undoubtably that would be biting me badly if Embacadero hadn't done such a good job of
the transition.
