Don't stop upgrading...
I have noticed over time that many organizations are picking LTSR and forgetting to upgrade. I have updated quite a few environments from 7.15 LTSR because they were so far behind the upgrade path.
What is LTSR?
LTSR (Long Term Service Release) provides stability and long-term support. It offers 5 years of mainstream and extended support.
Is this a good thing?
For organizations that wait a while between upgrades like 3 to 5 years, yes because during that time you are still within the support cycle.
Why is this becoming a bad thing?
Organizations are going beyond the 3 to 5 years cycle and also not keeping up with the cumulative updates. For instance, to upgrade to 2203 LTSR, you must be on at least 7.15 CU 5. If an organization installed 7.15, then it must choose a path to upgrade to the latest LTSR. Recently, this update required two separate maintenance windows. One to upgrade to 7.15 CU 5 and the 2nd to update to 2203 LTSR.
Choosing whether or not LTSR is the right path for you and your organization doesn't have to be a difficult decision. However, choosing LTSR does not mean you stop updating your environment. Consider Citrix CUs as Windows Updates. We patch to keep our environments healthy.
Don't let LTSR be a phrase that causes woes when it was meant to cause relief.
