You'll need to build a version 7.1.5 on your new hardware/VM and restore from backup onto new platform. you can then upgrade to 8.6.2.
If you are unable to re-build the 8.6.2 hardware then your only option is to use the import/export tool to export all configuration from the v7 and then import into v8 but you would lose historic CDR info.. but this retains configuration.
Not ideal you have an 8.6.2 already which is licensed when Cisco have/had a migration path a few years ago....
Hope this is useful

thanks for your answer.
I have already an installed 8.6.2 server with installed licences on a hardware platform.
so I don't want to re-install it from the 7.1.5 level.
I don't need any CDRs now.
will I receive the working 8.6.2 after the export of configs from 7.1.5 and the import of its into 8.6.2?

using the import/export tool should be fine. some subtle differences between v7 & v8 and you may need to run import of data several times due to some dependencies on config you are yet to import. As you are able to have both systems running you can test thoroughly before going live.
Alternatley, upgrade your v7 to v8.6 but you will need Cisco to re-host license from v7 to v8.

I have two CUCMs on hardware platforms - 7.1.5 and 8.6.2.
And I need to move all the configs from 7.1.5 to 8.6.2
The reason is simple - I cannot find phones for 7.1.5 to buy :)
As I understand the upgrade is the process when I make changes over my one CUCM.
And the migrate is when I move configs from one CUCM to another CUCM.

your 1st way is looking very good for me.
How do you think if I upgrade old system the old licences will work on it?
And if something will go wrong I will have on one working CUCM.

well so what is the main problem of moving configs by import-export from 7.1.5 to 8.6.2?
Will I get troubles which I don't see now?
in this case I will have two working CUCMs with the identical configs.
Ans I will be able to test the new one before the implementation.

OK, if I will try the next steps:
1. Make a DRS backup on an old CUCM 7.1.5.
2. Install a new virtual CUCM 7.1.5 for intermediate purposes.
3. Restore DRS backup from 1-st step on a virtual CUCM 7.1.5.
4. Upgrade a virtual CUCM 7.1.5 to the 8.6.2 version.
5. Make a DRS backup from a virtial 8.6.2 (ex-virtual 7.1.5)
6. Restore a DRS backup on a hardware 8.6.2 with existing licences.
Will it work?

I would suggest you to check with firstname.lastname@example.org first if they can re-host licenses for 8.6 ver, if they can, then either way you can choose. In above case you may need to re-host licenses after step 3 and before step 4.
