Incessant improvements, keep on introducing something new and regularly fixing the existing bugs are the key qualities of a successful Product. Sitecore is undoubtedly not an exception in this stream. Releasing timely version upgrades, intermediate updates and various patches is the beauty of Sitecore which makes it more powerful, extendable and robust.
As s result, these regular updates introduce the need to upgrade the current version we are using to the latest or most suitable one because – Upgrades Are Inevitable.
Frequently we observe that either our friends or colleagues or someone on various Sitecore community portals are keep on asking questions regarding Sitecore upgrade. I wont hesitate saying that at this moment as well someone somewhere in the world is either doing a Sitecore upgrade or planning for it or backlogged as a must to have Agile Story for the current/next fiscal year.
A team or a person who never did a Sitecore Upgrade, have a lot of questions/doubts to be answered/discussed like:
- What is the best migration approach from my version to latest/targeted version?
- How my databases/code/configuration files will be migrated?
- How the historical analytics data either from Analytics DB or xDB will be migrated?
- Which one is more efficient – Incremental Upgrades or Express Migration or Mixed Mode?
- I have various modules/third parties integrated with the project, what should be smoother upgrade priorities for those integrations?
- Is code/content freeze is mandatory while upgrading Production environment?
- How to deal with Licensing while introducing new servers during the upgrade?
- Should I stick to the on-premise mode or it’s time to migrate to Cloud?
- What should be the best scale-in/scale-out approaches for my Sitecore implementation?
- Which one to choose for xDB – SQL or Mongo?
Along with below questions asked on Sitecore Stack Exchange:
- Sitecore upgrade v7.2 to 9
- Possible upgrade strategy
- Upgrading from 7.2 to 8.2
- Sitecore upgrade strategy for multiple publishing targets
- What’s the best migration strategy for 6.5 to 8.2?
And some innocent questions like this:
I wish Sitecore Upgrades are that easy…
