I have 'upgraded' my site to SSL two weeks ago, and following the instructions given by Google, added the https:// version of the domain (which uses .htaccess to automatically redirect to the https://www.... version now) as an extra entry ('property') in Webmaster Tools ... but now, the statistics for the https:// version start only 2 weeks ago, while the ones for the http:// version end by then...
As a consequence, developments of certain things like Google Index status etc. are only partially displayed for each version - so if I focus on the SSL version from now on, I will 'lose' all those years of comparable data collected in Webmaster Tools.
Isn't there any way to 'combine' the data from both versions like Google Analytics seems to be able to (but which doesn't display half of the information Webmaster Tools can give me)?
