When upgrading from legacy to epoch manager-based index, we will write an intentionally-corrupted index blob, such that old clients won't be able to understand it when they read the repository index using legacy format. The error message emitted by very old clients is not great, but it's safer to do that rather than corrupt the repository. Note that this additional safety has a delay of up to 15 minutes which is the time required for old clients to stop relying on index list cache in case of very long-running snapshots, server or KopiaUI.
