Situation Description:
I am adminitering TM1 with some hundred users.
As Windows XP is running out of support in April 2014 we are migrating to Windows 8 and also Office 2013.
Then the only supported version of TM1 when using Windows 8 is TM1 10.2.
But TM1 10.2 is not usable so far - one reason is that comma values are not accepted in TM1 Web when having european formatting for numbers (#.###,00).
(will not be fixed before the second half of 2014 with FP2

Question:
What are your recommendations in this situation?
Which version to use and how to implement them?
I would like to keep TM1 9.5.2 and upgrade to 10.2 when at least the major bugs are fixed with FP2.
Thanks a lot in advance
Tilo
