+// TestGenerate13SampleDataForBackwardCompatibility is very similar to TestLedgerAPIs
+// however, this doesnot remove the ledgers created by the test. This is because, the sole
+// purpose of this test is to generate the ledgers from v1.3 code so that they can manually be
+// copied to future releases to make sure that the future releases can work with and can rebuild different
+// ledger components (state/indexes etc.) for the ledger that is built using v1.3 codebase
+// So, this test is marked as skipped in general.
+// For producing the v1.3 ledger,
+// 1) Make sure that the path '<peer.fileSystemPath>/ledgersData' ('/tmp/fabric/ledgertests/ledgersData') does not exist
+// 2) commentout the line 't.Skip()' and run this test in isolation
+// 3) move the folder '<peer.fileSystemPath>/ledgersData' to a separate place for copying over to a future release codebase
