If it is zero config and its persistent store is DHCP leases, then they will expire. OSPF advertisements would have aged out long ago. It might be worth redoing the router-id selection if it is well past the maxage limit and there are no adjacencies. If the router is just power cycled when moving, it should ask for certain IA-PD and may not get them (or make DHCPv4 requests for a specific address). The same link local requestors (or MAC on DHCPv4) would not be on the new LANs and so the old granted leases that had not expired would also do no harm. What persistent storage, beside configuration by the user would last more than a week? AFAIK just having DHCP leases lasting more than a week would also require some user configuration.
