In the process of moving my server, I encountered this error when using mongorestore:
assertion: 4 Missing expected field "currentVersion"
What does it mean? What should I do to restore from the dump directory?
The command I used was:
mongorestore dump
The problem was that the new server uses an outdated MongoDB -- version 2.6.
When installing it, I just retrieved it from the default repository.
I had some problems installing an up-to-date version as my server was 32-bit, forcing me to migrate to a 64-bit machine.
