I have a Cisco IDS 4235 device with license "<LicFileID>20040416051341665".
Software Version is 4.1(5)S227 (IDS-sig-4.1-5-S227.rpm.pkg)
I know that signature update is not possible for 4.x and thats the reason why Im going for 5.x & then to 6.x.
Is that possible to upgrade this to 5.x version ???
Pls check the license ID and suggest me how to take it forward.
