What I am really upset about is the loss of synchonised trees.
That was one of the best features.
That is the main thing that I will miss. I tend to work on my tree on line as I find it easier, but I know at the moment that it will then synchronise with FTM. Unless I remember to do this manually in the future everytime I use one or the other, I will soon have different trees.
As Millmoor indicated, Ancestry have said your copy of FTM will work after 1 Jan 2017, and have provided a
follow-up post to cover the enquiries they have received.
Up until 1 Jan 2017 everything will be as it is now, you just won't be able to buy copies after December 2015. After 1st Jan everything will continue, you just won't get bugfix updates or be able to get support from Ancestry on FTM related issues. There is no guarantee how long everything will work, so they have to state that caveat, but that's only if there are changes in 3rd party software that effects the functionality. They aren't going to stop allowing synch's etc just because the 1 Jan has been reached!
As an example, I was using FTM2012 on my desktop that was running MS Vista operating system. A change happened in Internet Explorer which meant I could no longer use FTM for online searches. I could use the website because I used non-microsoft browsers, but not FTM which relies upon IE. I did a back-up and moved FTM to my Windows 7 laptop, and all the in-app searches worked again.
So don't assume that you won't be able to continue to use your software after Jan 2017, as you will and with the functionality it currently has. If some functionality does eventually stop, it doesn't necessarily it can't be restored by changing your set-up.
Of course you may wish to take the time to look at other software if you feel that one with ongoing support would be better. You could then migrate when and if you feel ready, rather than be forced to.
