An accelerator deployment tool deploys multiple accelerators to multiple programmable devices, and detects when a new programmable device becomes available. When a first accelerator in a first programmable device is a better match to the new programmable device, the accelerator deployment tool automatically generates an image for the first accelerator for the new programmable device, deploys the image on the new programmable device to generate a second accelerator, changes references to the first accelerator to reference instead the second accelerator, and casts the first accelerator out of the first programmable device.
