# Test to check inplace upgrade from 7.6. The initial server upgrade
# phase i.e. the phase during which InnoDB and other SE tables are
# upgraded should not upgrade NDB tables. NDB tables are instead
# upgraded during the schema synchronization phase.
#
# For inplace upgrade with NDB tables, another requirement is to
# ensure that the tables are present in NDB Dictionary. This is
# done through restoring a 7.6 based backup created using the
# following SQL statements:
#
# CREATE DATABASE test;
# USE test;
# CREATE LOGFILE GROUP lg1
#   ADD UNDOFILE 'lg1_undofile.dat'
#   INITIAL_SIZE 1M
#   UNDO_BUFFER_SIZE = 1M
#   ENGINE NDB;
# CREATE TABLESPACE ts1
#   ADD DATAFILE 'ts1_datafile.dat'
#   USE LOGFILE GROUP lg1
#   INITIAL_SIZE 2M
#   ENGINE NDB;
# CREATE TABLE t1 (
#   a int PRIMARY KEY,
#   b varchar(255)
# ) ENGINE = NDB
#  TABLESPACE ts1
#  STORAGE DISK;
# INSERT INTO t1 VALUES (1, "Solskjaer has won it");
# CREATE DATABASE db1;
# USE db1;
# CREATE TABLE t1 (
#   a int PRIMARY KEY,
#   b varchar(255)
# ) ENGINE NDB;
# INSERT INTO t1 VALUES (1, "Manchester United have");
# INSERT INTO t1 VALUES (2, "Reached the promised land");
#
# This test does the following:
# 1. Stops both MySQL servers
# 2. Restores the NDB backup
# 3. Unzips the 7.6 data directories
# 4. Restarts both MySQL servers (step where the upgrade takes place)
# 5. Runs test DDL statements and queries
# 6. Clean up which includes restarting both MySQL servers
