Migrate ElastiCache to Azure Managed Redis

For developersElastiCache to Azure Managed Redis (AMR)

Before migrating to Azure Managed Redis, you should evaluate the migration and consider the best option. Read this guide to determine which migration strategy is right for you. Note: Reach out to our team for support on live migrations.

#Offline data migration

#Create an S3 bucket with proper permissions

Open Amazon S3 and create a new bucket. The ElastiCache backup and the Amazon S3 bucket that you create must be in the same AWS Region.

Creating a new S3 bucket in the AWS console

Navigate to your new S3 bucket and go to the Permissions tab

Under Access Control List (ACL), choose Edit. Select Add grantee,

Elasticache canonical ID (paste this in under Grantee): 540804c33a284a299d2547575ce1010f2312ef3da9b3a053c8bc45bf233e4353
Select Objects > List & Write
Select Bucket ACL > Read & Write

Configuring Access Control List (ACL) for ElastiCache backup

Under the Permissions tab still, add the following JSON to the Bucket Policy section. Replace UNIQUE-BUCKET-NAME with the name of your S3 bucket:

#Create a Backup from ElastiCache

Navigate back to your ElastiCache instance
Select the Actions button, and create a Backup

#Import RDB file to Azure Blob

In the Microsoft Azure console, navigate to Storage Accounts
Create an Azure Blob instance

#Create your Azure Managed Redis instance

Navigate to Azure Managed Redis
Select a size that fits your data set size captured in the initial steps on Memorystore. The rough estimate for sizing is your [current data set size * 1.2] = AMR data size (round up to the nearest size)

Sizing your Azure Managed Redis instance based on dataset size

Select the data modules that you used within your Memorystore instance (RediSearch, RedisJSON, RedisTimeSeries, RedisBloom)

Create your instance

#Import RDB file into Azure Managed Redis instance#

Navigate to your instance once it’s been created
Go to Administration > Import Data
