Introduction

Prerequisites

Warning

This guide assumes that your cluster is running MemSQL v7.0 or later, which can be verified via memsql-ops memsql-list.

If your cluster is running an earlier version of MemSQL, it will be upgraded to MemSQL v7.0 as part of this migration.

In addition, this guide assumes:

The SingleStore cluster components were installed via rpm, yum, apt, or dpkg. To verify that the cluster was created via package install, run the following commands on the Linux command line.

Red Hat Distribution:
Shell
```
sudo yum list --installed | grep memsql-toolbox --or--
sudo yum list --installed | grep singlestoredb-toolbox --or--
rpm -qa | grep memsql-toolbox --or--
rpm -qa | grep singlestoredb-toolbox
```
Debian Distribution:
Shell
```
dpkg -s memsql-toolbox | grep Status --or--
dpkg -s singlestoredb-toolbox | grep Status
```
If none of these packages are installed, the cluster was likely deployed via tarball, and so the non-sudo version of the Ops to Tools migration guide should be followed instead.
The user that created the cluster has sudo privileges.
The user performing the migration has sudo privileges.
A root password has been set on all nodes in the cluster Learn how to set root password.
The SingleStore cluster is managed by MemSQL Ops v7.0 or later, which can be verified via memsql-ops agent-list Learn how to upgrade.
SingleStore Toolbox v1.3.0 or later, which can be verified via sdb-toolbox-config version Learn how to upgrade.

Ensure that the following ports are open for use:

Port	Type	For
22	Inbound/Outbound	SSH / SFTP
80	Inbound/Outbound	MemSQL Ops
443	Inbound/Outbound	SingleStore repository connection
3306	Inbound/Outbound	SingleStore (default)

The installing user must be able to log into each host via ssh.

Host

A host is a physical or virtual machine.

Node

In SingleStore parlance, a node is a SingleStore database component of type aggregator or leaf.
