The following views are not created when the replica set has already been initiated. repl::createOplog() is called (1) as part of the replSetInitiate command and (2) as part of initial sync. This means the views won't be created when upgrading from an existing replica set.

createSlimOplogView(opCtx, ctx.db());
tenant_migration_util::createOplogViewForTenantMigrations(opCtx, ctx.db());

These lines should be relocated so they are done as part of startup (at minimum after the storage engine has been initialized).
