Download Customer's NAV2015 license

Question

We would download an old license because our customer (passed to BC) need to view old data on NAV2015 and we need a new DB with the original license on NAV2015.

Customer didn't store the old file .flf on the server, but we can't download .flf from PartnerSource

Please let we know

Answer 1

NAV 2015 requires a NAV 2015–version license key; older or newer license versions are not compatible.

If the original NAV 2015 .flf file is no longer stored on the customer’s systems and cannot be downloaded from PartnerSource, the license must be re‑obtained through the official licensing channels rather than from the product itself. The context available here only states:

• NAV 2015 can only run with a valid NAV 2015 license file.
• NAV 2015 license keys are versioned and are not compatible with NAV 2013/2013 R2, and vice versa.
• New NAV 2015 licenses or transition upgrades are ordered and managed via Microsoft’s licensing systems (Order Central / partner licensing flows), and license information is obtained from there.

Based on this, the practical options are:

1. Use the customer’s existing NAV 2015 license entitlement
   • If the customer had an active enhancement plan and was upgraded to NAV 2015, the NAV 2015 license is tied to that agreement.
   • The partner or customer licensing admin must retrieve the NAV 2015 license from the appropriate Microsoft licensing portal (Order Central/Partner licensing site) using the customer’s agreement details. The license cannot be recreated from NAV 2015 itself.
2. Use downgrade rights from a later license (if applicable)
   • If the customer’s license was later upgraded (for example to NAV 2016 or Business Central) and downgrade rights apply, the partner can request the appropriate NAV 2015 license via the licensing channel using those downgrade rights.
3. Ensure the correct version when restoring/creating the NAV 2015 database
   • When the NAV 2015 license is obtained, it must be a NAV 2015 license key; NAV 2016 or other versions are not compatible with NAV 2015 and cannot be used to run a NAV 2015 database.

There is no supported method in the provided material to download or regenerate the customer’s NAV 2015 .flf directly from PartnerSource if it is not visible there; the resolution is to work through the licensing/ordering channel (partner licensing tools or Microsoft support for licensing) using the customer’s agreement and license details.
