Questions about switching from Amazon to Google version?

[Trippdee]

I have the Amazon version installed.

Amazon DS ver .74
Google DS ver .76 does not offer upgrade
Google DS Tropic ver .75

If I install Google Tropic ver will it copy my id and dragons and can I then uninstall the old Amazon ver?

If the above is true should I then install and switch to the non Tropic. 76 ver?

thanks for the help. :)
