Version upgrading method and device, electronic equipment and storage medium

The invention discloses a version upgrading method and device, electronic equipment and a storage medium, and relates to the technical field of software upgrade. The version upgrading method comprises the steps: obtaining a target upgrading package; analyzing the target upgrade package to obtain a target partition of the target upgrade package; acquiring a local partition corresponding to the target partition; verifying the target partition and the local partition to obtain a target verification value corresponding to the target partition and a local verification value corresponding to the local partition; if the target verification value is different from the local verification value, erasing the local partition; and performing version upgrading according to the erased local partition. According to the version upgrading method, the probability that the NVR cannot be normally started due to upgrading failure during software upgrading of the network video recorder can be reduced, and meanwhile, the software up
