Microsoft’s roadmap for rolling out Windows 10 to older Lumia handsets running version 8.1 of the OS has been leaked online. While the company previously confirmed it would provide the update to all its handsets with a minimum of 8GB of internal storage, it didn’t announce when the upgrade would take place.
The new leak supposedly comes courtesy of telecom provider Orange Poland. According to the report, Microsoft plans to push Windows 10 out in two phases. The first will begin on December 14 and involves a smaller pool of models consisting of the Lumia 630, Lumia 635, Lumia 640, Lumia 735, and Lumia 830.
The next wave may happen much later on February 1 of next year. A larger number of handsets are set to receive the update in this round including the Lumia 520, Lumia 532, Lumia 625, Lumia 720, Lumia 820, Lumia 920, Lumia 925, Lumia 930, Lumia 1020, and Lumia 1320. Notably, the Lumia 530 and Lumia 1520 are not part of either rollout phase.
The exclusion of the former makes sense as it contains only 4GB of internal memory and is thus not eligible to get the upgrade. The latter is trickier to explain, with GSM Arena speculating that it may be because the handset was only sold unlocked in Poland, so Orange would not directly have anything to do with its update process.
Lumia users should keep in mind these dates are specifically for Poland and may not be followed in other countries. Still, it provides a rough sketch of when Microsoft is planning to start beaming out Windows 10 to older devices. The tech giant is set to debut the new mobile OS with the Lumia 950, Lumia 950 XL and Lumia 550 within the next few weeks.
