Version changes
Product lifecycle updates
End-of-life policy extension
The end-of-life policy for Redis Enterprise Software versions 6.2 and later has been extended to 24 months after the formal release of the subsequent major version. For the updated end-of-life schedule, see the Redis Enterprise Software product lifecycle.
Supported upgrade paths
Redis Enterprise Software versions 6.2.4 and 6.2.8 do not support direct upgrades beyond version 7.4.x. Versions 6.2.10, 6.2.12, and 6.2.18 are part of the upgrade path. To upgrade from 6.2.4 or 6.2.8 to versions later than 7.4.x, an intermediate upgrade is required.
The next major Redis Enterprise Software release will still bundle Redis database version 6.2 and allow database upgrades from Redis database version 6.2 to 7.x.
See the Redis Enterprise Software product lifecycle for more information about release numbers.
Deprecations
API deprecations
-
The replica HA cluster policy is deprecated.
-
The maintenance mode option
keep_slave_shards
is deprecated inrladmin
and the REST API. Useevict_ha_replica
andevict_active_active_replica
instead. -
/v1/debuginfo
REST API paths are deprecated. Use the new paths/v1/cluster/debuginfo
,/v1/nodes/debuginfo
, and/v1/bdbs/debuginfo
instead.
Legacy UI deprecation
The legacy UI is deprecated in favor of the new Cluster Manager UI and will be removed in a future release.
Redis 6.0 database deprecation
Redis database version 6.0 is deprecated as of Redis Enterprise Software version 7.4.2 and will be removed in a future release.
To prepare for the future removal of Redis 6.0:
-
For Redis Enterprise 6.2.* clusters, upgrade Redis 6.0 databases to Redis 6.2. See the Redis 6.2 release notes for the list of changes.
-
For Redis Enterprise 7.2.4 and 7.4.x clusters, upgrade Redis 6.0 databases to Redis 7.2. Before you upgrade your databases, see the list of Redis 7.2 breaking changes and update any applications that connect to your database to handle these changes.
End of triggers and functions preview
The triggers and functions (RedisGears) preview has been discontinued.
-
Commands such as
TFCALL
,TFCALLASYNC
, andTFUNCTION
will be deprecated and will return error messages. -
Any JavaScript functions stored in Redis will be removed.
-
JavaScript-based triggers will be blocked.
-
Lua functions and scripts will not be affected.
If your database currently uses triggers and functions, you need to:
-
Adjust your applications to accommodate these changes.
-
Delete all triggers and functions libraries from your existing database:
-
Run
TFUNCTION LIST
. -
Copy all library names.
-
Run
TFUNCTION DELETE
for each library in the list.
If any triggers and functions libraries remain in the database, the RDB snapshot won't load on a cluster without RedisGears.
-
-
Migrate your database to a new database without the RedisGears module.
RedisGraph end of life
Redis has announced the end of life for RedisGraph. Redis will continue to support all RedisGraph customers, including releasing patch versions until January 31, 2025.
See the RedisGraph end-of-life announcement for more details.
Operating system retirements
- RHEL 7 and Oracle Linux 7 were previously announced as deprecated in the Redis Enterprise Software 7.2.4 release notes. As of Redis Enterprise Software 7.4.2, RHEL 7 and Oracle Linux 7 are no longer supported.
Security retirements
-
The RC4 encryption cipher, which was previously deprecated in favor of stronger ciphers, is no longer supported.
-
The 3DES encryption cipher, which was previously deprecated in favor of stronger ciphers like AES, is no longer supported. Verify that all clients, applications, and connections support the AES cipher.
-
TLS 1.0 and TLS 1.1 connections, which were previously deprecated in favor of TLS 1.2 or later, are no longer supported. Verify that all clients, applications, and connections support TLS 1.2 or later.
Upcoming changes
Default image change for Redis Enterprise Software containers
Starting with the next major version, Redis Enterprise Software containers with the image tag x.y.z-build
will be based on RHEL instead of Ubuntu.
This change will only affect you if you use containers outside the official Redis Enterprise for Kubernetes product and use Ubuntu-specific commands.
To use Ubuntu-based images after this change, you can specify the operating system suffix in the image tag. For example, use the image tag 7.4.2-216.focal
instead of 7.4.2-216
.
Supported platforms
The following table provides a snapshot of supported platforms as of this Redis Enterprise Software release. See the supported platforms reference for more details about operating system compatibility.
✅ Supported – The platform is supported for this version of Redis Enterprise Software and Redis Stack modules.
⚠️ Deprecation warning – The platform is still supported for this version of Redis Enterprise Software, but support will be removed in a future release.

The RHEL-compatible distributions CentOS, CentOS Stream, Alma, and Rocky are supported if they have full RHEL compatibility. Oracle Linux running the Red Hat Compatible Kernel (RHCK) is supported, but the Unbreakable Enterprise Kernel (UEK) is not supported.
-
The server version of Ubuntu is recommended for production installations. The desktop version is only recommended for development deployments.
-
See the Redis Enterprise for Kubernetes documentation for details about support per version and Kubernetes distribution.
-
Docker images of Redis Enterprise Software are certified for development and testing only.
Known issues
-
RS131972: Creating an ACL that contains a line break in the Cluster Manager UI can cause shard migration to fail due to ACL errors.
-
RS61676: Full chain certificate update fails if any certificate in the chain does not have a Common Name (CN).
-
RS119958: The
debuginfo
script fails with the error/bin/tar: Argument list too long
if there are too many RocksDB log files. This issue only affects clusters with Auto Tiering. -
RS122570: REST API
POST /crdbs
responds with a confusing error message if the cluster does not have the requested CRDB-compatible module that complies with the requested featureset.This issue was fixed in Redis Enterprise Software version 7.4.2-126.
-
RS123142: In an Active-Active setup with at least three participating clusters, removing and re-adding a cluster after removing older clusters without re-adding them can cause missing keys and potentially lead to data loss or data inconsistency.
To prevent this issue, avoid adding clusters until you upgrade to the upcoming maintenance release when available.
This issue was fixed in Redis Enterprise Software version 7.4.2-169.
Known limitations
New Cluster Manager UI limitations
The following legacy UI features are not yet available in the new Cluster Manager UI:
-
Remove a node.
Use the REST API or legacy UI instead. See Remove a cluster node for instructions.
-
Purge an Active-Active instance.
Use
crdb-cli crdb purge-instance
instead. -
Search and export the log.
OpenSSL compatibility issue for 7.4.2 modules on Amazon Linux 2
Due to an OpenSSL 1.1 compatibility issue between modules and clusters, Redis Enterprise Software version 7.4.2-54 is not fully supported on Amazon Linux 2 clusters with databases that use the following modules: RedisGears, RediSearch, or RedisTimeSeries.
This issue will be fixed in a future maintenance release.
RedisGraph prevents upgrade to RHEL 9
You cannot upgrade from a prior RHEL version to RHEL 9 if the Redis Enterprise cluster contains a RedisGraph module, even if unused by any database. The RedisGraph module has reached End-of-Life and is completely unavailable in RHEL 9.
Cannot create Redis v6.x Active-Active databases with modules
You cannot create Active-Active databases that use Redis version 6.0 or 6.2 with modules. Databases that use Redis version 7.2 do not have this limitation.
This limitation was fixed in Redis Enterprise Software version 7.4.2-104.
Firewalld configuration fails on RHEL 9 due to file permissions
When you install Redis Enterprise Software version 7.4.2 on RHEL 9, firewalld
configuration fails to add the redislabs
service if /etc/firewalld/services/redislabs-clients.xml
and /etc/firewalld/services/redislabs.xml
are owned by redislabs
instead of root
.
As a workaround:
-
Change the files' owner and group to
root
:$ chown root:root /etc/firewalld/services/redislabs-clients.xml $ chown root:root /etc/firewalld/services/redislabs.xml
-
Add the
redislabs
service tofirewalld
:$ systemctl daemon-reload $ systemctl restart firewalls $ /bin/firewall-cmd --add-service=redislabs
This limitation was fixed in Redis Enterprise Software version 7.4.2-129.
