Techniques include receiving, from a first remote computing device, a message associated with at least one controller; extracting, based on the received message, an image of software associated with the at least one controller; accessing, based on the extracted image, a delta file; and transmitting the accessed delta file to a second remote computing device. ## Claims ### Claim 1 A non-transitory computer-readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for efficiently providing controller data as part of a maintenance or update process, the operations comprising: receiving, from a first remote computing device, a message associated with at least one first controller and comprising an identifier; extracting, based on the received message, an image of software associated with the at least one first controller; generating a delta file, the generating comprising: determining a stored image of software using the identifier; comparing the extracted image of software to the stored image of software; and based on the comparison, determining differences between the extracted image of software and the stored image of software, the delta file representing the differences; and transmitting the generated delta file to a second remote computing device for updating software on at least one second controller. ### Claim 2 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein: the identifier is a software image identifier; and the stored image of software is associated with metadata comprising at least one of: a delta file identifier, a version identifier, a controller identifier, a device identifier, a system identifier, a date, a timestamp, a software source identifier, or a file format. ### Claim 3 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the transmitted delta file is configured to be flashed to the second remote computing device. ### Claim 4 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the transmitted delta file is configured for a program to construct an image based on the transmitted delta file. ### Claim 5 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the message was transmitted by the first remote computing device in response to scanning at least part of a controller system. ### Claim 6 (depends on 1) The non-transitory computer-readable medium of claim 1, the operations further comprising verifying an authenticity of the message. ### Claim 7 (depends on 6) The non-transitory computer-readable medium of claim 6, wherein verifying the authenticity of the message comprises validating a signature included in the message. ### Claim 8 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein: the at least one second controller includes a replacement controller; and the message was transmitted by the first remote computing device in response to scanning the replacement controller. ### Claim 9 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the stored image of software was previously extracted from another message. ### Claim 10 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the extracted image is a binary image. ### Claim 11 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the stored image of software is associated with the identifier. ### Claim 12 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the generated delta file represents differences between different dimensions of software. ### Claim 13 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the generated delta file is transmitted to the second remote computing device in response to a prompt. ### Claim 14 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the prompt is generated in response to a determination that software on the at least one second controller is underperforming. ### Claim 15 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the prompt is generated in response to a determination that software on the at least one second controller corresponds to a version identifier not satisfying a reference identifier. ### Claim 16 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the stored image is a most recently stored image of software for controllers associated with the identifier. ### Claim 17 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the delta file is generated in response to a determination that no stored images in a location correspond to the extracted image. ### Claim 18 (depends on 1) The non-transitory computer-readable medium of claim 1, wherein the delta file is generated as the image of software associated with the at least one first controller is extracted. ### Claim 19 A method for efficiently providing controller data as part of a maintenance or update process, the method comprising: receiving, from a first remote computing device, a message associated with at least one first controller and comprising an identifier; extracting, based on the received message, an image of software associated with the at least one first controller; generating a delta file, the generating comprising: determining a stored image of software using the identifier; comparing the extracted image of software to the stored image of software; and based on the comparison, determining differences between the extracted image of software and the stored image of software, the delta file representing the differences; and transmitting the generated delta file to a second remote computing device for updating software on at least one second controller. ### Claim 20 (depends on 19) The method of claim 19, wherein the transmitted delta file is configured for a program to construct an image based on the transmitted delta file.
