From the U. S. Department of Energy's Office of Electricity:

On April 6, 2019, there will be an event affecting the electric transmission and distribution system that has industry concerned about the potential for a major disruption.  During the Week Number rollover of the Global Positioning System (GPS), the week number that uses the 10-bit binary system will reach its limit of 1,024 weeks and will be forced to roll over and be reset to week 0.

For more details, please read this excellent article by Gavin Schrock, PLS at xyHt Magazine.

This is Leica's response on there "Myworld" website. They have been affected by these rollovers in the past, so will be crossing my fingers at 12:01am.

"GPS Week Rollover

Occurring 6 April 2019, the transmitted GPS week number in the navigation message will rollover from 1023 to 0. All currently operational Leica Geosystems GNSS receivers will not be affected by this rollover.
Nevertheless, to ensure the best possible performance, it is a good practise to use the latest firmware. Please refer to the myWorld portal or contact your local Leica Geosystems representative to obtain the latest firmware versions."

Topcon also has a list of receivers that will get the firmware upgrade and which ones will not.
