multi data center upgrade from 4.17.05 to 4.18.01

Hi,

We have an on prem 4.17.05 setup with multi dc. We want to upgrade the setup to 4.18.01.

Do we have to perform the upgrade for individual datacenter as given in the upgrade document, i.e dc-1 first and then dc-2 or are there any specific steps to upgrade a multi-dc setup ?

Also, do we have to use the silent config used for the single setup or the one used to setup the multi-dc ?

Thanks

Yes. You need to follow the sequence depending on the topology.we recently did from 4.16.09 to 4.18.01 and it is not complex as what we thought initially. We took assistance from apigee expert service who are very helpful.If it is complex topology would recommend to go with expert service to understand and avoid any issues.

All upgrades are done via silent installation & well documented in below link

https://docs.apigee.com/private-cloud/v4.18.01/update-apigee-edge-4170x-41801

Thanks Vinay. The document says that the upgrade should be done simultaneously for both dcs.

Eg: update cassandra ans zookeeper for dc1 and dc2

update qpidd for dc1 and dc2

update ldap for dc1 and dc21

......... etc

We asked apigee support and they responded saying we should do one dc at a time, hence a little confused.

Thanks

It depends on how your topology is set and you need to maintain the zookeeper/cs quorum or analytics setup(active-passive/active-active)/ldap(active-active) setup etc. I can provide the details once you give more information on your topology.
