After the mirror image checking is finished, substantially can determine the systemic-function no problem, can carry out mirror image this moment activates, mirror image activates and exactly existing network version and redaction is carried out blocked operation, use redaction that service externally is provided, stop the operation of existing network version simultaneously, thereby finish whole upgrade process.This step is in whole upgrade process, just activation manipulation may bring professional short interruption, but this process is very short, can ignore, this step is finished by mirror image mobilizing function in the image upgrade assistant system, and integrated system running state is monitored and handoff functionality.
This step just stops the operation of existing network version software, does not destroy existing network version software state, thus the handled easily rollback.
Step S105: upgrading back version if wait other reason because the user is dissatisfied, need carry out rollback and handle after externally providing business service, then stops current existing network version software, and promptly the mirror image after the upgrading starts original existing network version software.
This step is the step after mirror image activates; be applicable to the special circumstances that to carry out rollback; such as new system in use the user feel not as original system handy; the strong request rollback in this time, uses this step can directly start original system service externally is provided; and close new system; thereby reach the purpose of rollback, this step is finished by unusual rollback function in the image upgrade assistant system, and rollback operation fast, simply.
In order to realize said method, the present invention also provides a kind of image upgrade device, as shown in Figure 2, comprises mirror image generation module 21, upgrading module 22, operation control module 23, and authentication module 24, wherein:
