To update or not to Update Rollup? That is the question

Some time ago I wrote a parody about Dynamics CRM blogs that mainly seem to post news about the latest Update Rollups being released. Now I find myself writing an Update Rollup blog post myself. Is that a sign that I’ve run out of topics and slipped into the autopilot blogging mode? I hope not, but after reading quite a lot about the latest Update Rollup 10 for Dynamics CRM 2011 I decided to contribute a bit into the discussion.

It’s always great to receive improvements to the software you spend all your days working with, isn’t it? Compared to a product like Java which Oracle promises to patch only four times a year, even if it’s about critical security updates (did you remember to uninstall your Java 7 yet?), Microsoft is doing quite an OK job with their update process and we see a steady stream of releases to make Dynamics CRM better one bit at a time. Even though Update Rollup 9 was cancelled after the beta program, MS is now back on track with their release schedule in the form of UR10 that came out two weeks ago.

We have once again a great in-depth article from Dynamics CRM in the Field about all things Update Rollup 10. It tells all the details of the story from Microsoft’s perspective, but let’s evaluate the ups & downs of this latest release from the Dynamics CRM community perspective to get a complete picture, shall we? OK, here goes:

The Ups

There was quite a number of fixes promised for the CRM Outlook client in Update Rollup 10 that would potentially solve some of the stability issues many users have encountered when trying to use the CRM Outlook client for actual work in their environment. It’s now 2 years since the first beta of the completely rewritten Dynamics CRM Outlook client came out and many of us are certainly hoping that it would have reached a mature enough level where you don’t have to be afraid of if causing a flood of tickets to your helpdesk. Yes, some users may be quite happy with it as it is, but you’d be foolish not to prepare for potential issues when planning a large scale deployment of the Outlook client. Reaching that good ol’ Service Pack 2 type of confidence level would be just great.

Another promising deliverable from UR10 is the improvements to query performance on large data sets. A new version of the performance optimization whitepaper has been released alongside the update, which describes the new options made available to tune the Quick Find performance. If you read the results of these tests by Chris Cognetta where the query time was decreased by over 80% in an environment with 1.5 million rows, it’s obvious this is an update worth paying attention to if you have or expect to have some “big data” in your CRM system.

Finally, as many MSDN subscribers are now eagerly updating their PC’s to run Windows 8, Internet Explorer and even the Office 2013 Preview, the added support for all of these in CRM 2011 Update Rollup 10 is reason enough to grab the very latest CRM bits. Just don’t forget that UR10 alone is not enough, there’s some things you should know about Windows 8 RTM & CRM 2011.

The Downs

So, we now have a Quick Find that is working faster, which means it must be doing something differently, right? It is, and unfortunately in some cases this will result in a Generic SQL Error message being shown to the user. It appears that the new update is not quite comfortable dealing with a set of Quick Find columns that contains address fields. As some of you may remember, the address 1 & address 2 fields on the account & contact forms are actually not stored in the same database table as the rest of the default fields, rather they reside in the CustomerAddressBase table. The UR10 version of Quick Find may therefore not work properly if you try to search for records based on address fields like city or zip code. Yes, Microsoft says using these as search fields is against best practices, but the users will very often want to narrow down the customer data based on geographic variables, so taking it away from them can only act as a workaround until we have a new hotfix from MS.

CRM developers might not be too concerned with performing actual queries on live customer data, but they will certainly be annoyed when encountering the following prompt after editing a JavaScript web resource: You have exceeded the maximum number of 200 characters in this field; it will be truncated. Doh! Making small changes to script files just became very tedious until Update Rollup 11 rolls along in 2 months time. Again, there’s a workaround to it (don’t use the editor, instead upload the file or use some helpful web resource tool from CodePlex), but it doesn’t really make anyone want to rush UR10 onto all their servers.

Then we have stories of people applying UR10 and finding they can’t access any of their CRM organizations, due to an unhandled exception: Method not found: ‘Void Microsoft.Xrm.Sdk.Query.FilterExpression.set_IsQuickFindFilter(Boolean)’. Uninstalling UR10 appears to be the only known cure for this show stopper, which obviously is related to the aforementioned Quick Find changes on some level.

Alternatively, if you’ve updated your CRM server from 4.0 to 2011, you may experience errors when trying to import a solution file: The element ‘savedquery’ has incomplete content. List of possible elements expected: ‘LocalizedNames’. Manually editing the XML to remove a view prior to importing the file is the available workaround, but again it can make the life of a system customizer quite difficult until there’s a fix available.

OMG, what should we do with these UR’s?!

The short answer is: always test first, then evaluate the ups & downs for your particular case. If you are struggling with the Outlook client, face performance issues with your huge CRM database or simply want to run CRM 2011 on Windows 8, going for Update Rollup 10 may be perfectly sensible for you. For someone who doesn’t have a compelling need to update, you may well decide to wait a bit longer and no one should blame you for it.

That’s pretty much how it is with any Update Rollup. In reality there’s never going to be the perfect time to update. Knowing ahead what hotfixes will deliver the biggest gains for you or potentially break your CRM deployment would be a great skill to have. Instead of dreaming about it, here’s a few guiding principles I would recommend you to follow:

• Always test the updates in your own test environment before planning live deployment. A virtual machine with your solutions & data is a good compromise, identical hardware is for people with enterprise level budgets (and problems).
• Never be the first to update, always wait a couple of weeks from the release and read the CRM forums for experiences from others. Trust the wisdom of the crowds.
• Coordinate the server and client update schedules to limit possible issues and maximize the benefits from the updates. While mixed environments tend to be supported, why risk it?
• Do update your CRM. Staying too far behind in this “cloud first” era can soon turn out to be an expensive strategy, so reserve adequate time and resources for keeping your CRM up to date – on a regular schedule.

Do you have any words of advise for people who are struggling with the “should I update to Update Rollup X” question? What’s your survival strategy?

Edit 2012-09-09: Based on the discussions on the Dynamics CRM Forum, I’ve created a new wiki page for Microsoft Dynamics CRM 2011 Update Rollup 10 on the CRM Wiki on Technet. The purpose is to provide a single place where the Dynamics CRM community members could share their information on potential issues and known problems that they encounter when applying the latest Update Rollups, as well as naturally links to any solutions or workarounds that can help others who are struggling with the same problem. I’ve initially added links to 10 suspected issues with UR10, but you are very welcome to contribute by adding new links or additional information to the wiki page. In an ideal world, we could have similar pages for each new rollup that gets released and be able to more easily identify both the benefits and the dangers or applying the updates into our CRM environments. Let’s see if the wiki can serve us as a platform for such information sharing.
