The Sony Reader Store has been dead for about a week now, and I finally got instructions on how to transfer my Sony account to Kobo.
The process was far simpler than I expected. All i had to do was click the link in the email, and then after I was directed to the Kobo website I clicked the button labeled Get Started. Everything after that happened automatically.
Of course, the fact that I already had an account with Kobo and I never did buy any ebooks from the Sony Reader Store, may have helped. One could argue that I didn't go through the full process.
Have you gotten the email yet? Did you lose any ebooks in the transfer process?
If you haven't transferred your account yet, I would do it soon. Sony has stated that the store credits will only be transferable until 31 May 2014, and it's better to transfer the credits than it is to let them go to waste.
In related news, Sony is also promising that they will be sending out an update for the Sony Reader next month. The PRS-T1, PRS-T2, and PRS-T3, will be getting an update that replaces the integrated ebookstore with one that is tied to Kobo. A second later update will add the ability to buy ebooks from Kobo directly, saving readers the effort of transferring the ebooks over a USB cable.
