Here's a link regarding Cisco Device Led Conversion (DLC).
In a previous post, I've mentioned about the Cisco Smart License in a Cisco ISR 4K router. Below are the steps in preparing a Cisco ISR 4K router with no Smart License and convert its Traditional Product Activation Key (PAK) License to Smart License using DLC.
1. Perform the ROMMON firmware and IOS-XE Upgrade:
In this scenario, I got a Cisco ISR 4K router running IOS-XE 16.6 which is doesn't have the Smart License enabled yet and has a Unified Communication (UC) PAK license installed. The target code is IOS-XE 16.12 which requires a Smart License and I'll perform a DLC on the UC license.
Refer to this link for the ROMMON and IOS-XE software code compatibility matrix.

I skipped the ROMMON firmware upgrade since the 4K router is already on the latest 17.x firmware and it wouldn't allow you perform a ROMMON 17.x > 16.x code "downgrade."
For reference, the ROMMON upgrade command is issued in privileged EXEC mode.

2. Configure Call Home:
I'm using the 4K dedicated GigabitEthernet0 Out-of-Band (OOB) interface which has the default Mgmt-intf VRF. I'm also using an On-Prem Cisco Smart Software Manager (CSSM) Smart License server. The config also works with the Cisco Smart License public portal over the Internet. Below are some additional Call-Home config.
ip name-server vrf Mgmt-intf <PRIMARY DNS IP> <SECONDARY DNS IP>
ip domain lookup
ip domain lookup vrf Mgmt-intf source-interface GigabitEthernet0
ip http client source-interface GigabitEthernet0
license smart url https://<CSSM FQDN>/Transportgateway/services/DeviceRequestHandler
license smart transport smart

destination address http https://<CSSM FQDN>/Transportgateway/service/DeviceRequestHandler
3. Generate a Product Instance Registration token in CSSM and apply in ISR 4K
Generate a Product Instance Registration token in CSSM, go to Inventory > General > New Token.
Issue the license smart register idtoken <CSSM TOKEN> force command in privileged EXEC.
4K#license smart register idtoken <CSSM TOKEN> force
Registration process is in progress. Use the 'show license status' command to check the progress and result

If you get a CRL log error, apply this workaround command and apply the registration token again:
crypto pki trustpoint SLA-TrustPoint
revocation-check none
4K#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
4K(config)#crypto pki trustpoint SLA-TrustPoint
4K(ca-trustpoint)#revocation-check ?
crl Revocation check by CRL

3. Initiate Device Led Conversion (DLC)
The final step is to issue the license smart conversion start privileged EXEC command to start the DLC conversion process.
4K#license smart conversion start?
clear Clear

deregister deregister this device
export Get or return an export authorization key
factory Execute Smart Licensing Factory commands
register register token id

stop Stop a license conversion that pending retry because of a communications failure
4K#license smart conversion start
Aug 23 03:52:40.593 UTC: %SMART_LIC-6-CONVERT_START: Smart License Conversion has started
You can check the DLC status with the show platform software license dlc command. This would take around an hour to complete per the Cisco Smart License doc.

If you go to CSSM Inventory > Product Instances, you'll see an Alert that DLC has been requested and a Synchronization is required.
If the DLC status is still not yet completed after waiting for an hour, you can perform a "force update" in the On-Prem CSSM. Go to CSSM Admin Workspace > click Synchronization.
Select the Virtual Account > click Sync Selected.
Select again the Virtual Account > click Actions > Network Synchronization > Standard Synchronization Now.
Notice under Alerts status changed to Synchronization Successful.
You can verify if the DLC and License migration is complete in On-Prem CSSM > go to License Tab > check the Available to Use and In Use. Notice there's a ISR_4400_UnifiedCommunication Smart License that would appeared with a Available to Use and In Use balance count of 1.
