<!-- This issue tracker is only for technical issues related to Bitcoin Core. General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange at https://bitcoin.stackexchange.com. For reporting security issues, please read instructions at https://bitcoincore.org/en/contact/. If the node is "stuck" during sync or giving "block checksum mismatch" errors, please ensure your hardware is stable by running memtest and observe CPU temperature with a load-test tool such as linpack before creating an issue! -->
<!-- Describe the issue --> I used bitcore version 0.9 to mine in 2019 and managed to mine some BTCs, they were validated and the balance appeared on the main screen, and in the full description this is generated and confirmed several times but since November 2019 I can't synchronize the system, it crashed in 37 weeks, and the problem is that when I copy this wallet and put it in a more current bitcore version it does not confirm the mined BTCs and there is no balance.
Expected behavior
<!--- What behavior did you expect? -->
Initially, there is a command that forces the system to synchronize, and another way to import the mined BTCs with the validations and information from the old version.
Actual behavior
<!--- What was the actual behavior (provide screenshots if the issue is GUI-related)? --> The system starts normally, at the bottom the synchronization message, but there is no change in the evolution bar, another thing that draws attention is that in the information tab there are only 10,746 blocks of 640,000 blocks, that is, some bug occurred that created this instability .
To reproduce
<!--- How reliably can you reproduce the issue, what are the steps to do so? -->
