Converting your existing Db2 instances to a Db2 pureScale environment

Converting your existing Db2 instances to Db2 pureScale requires that you update your instance to a Db2 pureScale instance .

Before you begin

Review the information in Planning to convert your environment to a Db2 pureScale environment.
Carry out the steps in Pre-conversion tasks for Db2 pureScale environments.
If your database is using the Db2 Partitioned Database Environment, you must convert your database to a single partition database before enabling to Db2 pureScale .

About this task

This task describes the steps for converting your existing instances to a Db2 pureScale environment. Some steps in this topic require that you are logged in as root.

Procedure

As root, convert the instance to a Db2 pureScale instance by issuing the db2iupdt command.
For details on how to convert your Db2 V11.5 instance to a Db2 pureScale instance, see Updating an instance to a Db2 pureScale instance using the db2iupdt command.
Create a backup of your database using the BACKUP DATABASE command. For example,
```
db2 BACKUP DATABASE database_alias TO /db2home/db2inst1/backup/
```

Verify the instance conversion is successful by connecting to the databases and issuing a small query, as shown in the following example:

 db2 connect to sample

                  Database Connection Information

                  Database server = DB2/AIX64 10.5.0
                  SQL authorization ID = TESTDB2
                  Local database alias = SAMPLE

                  db2 select * from syscat.dbauth

Add additional members or cluster caching facilities by using the db2iupdt command or db2isetup command.
A typical Db2 pureScale environment has two cluster caching facilities (CFs) and two members . For further details, see Adding new members or an additional CF .

What to do next

Perform post-conversion tasks for a Db2 pureScale environment.
