Posted on by Community Member

We are planning to upgrade our CRM instance from Dynamics 2011 to 365 On prem.  Can  some one please let me know how much time these projects typically take. We have very few customizations.  We need to upgrade Dev, Test and Production. Any help, or project plan is really appreciated.

    Hi Harsh,

    as you are need to do On-Premise to On-Premise upgrade, it would be straight forward (provided you don't need any customization enhancement in 365). You may also need to discuss & plan if you want to go for inplace uprade or migration.

    Refer this link: technet.microsoft.com/.../hh699716.aspx

    The only think you need to think about is... do you have any unsupported customization, javascript or any HTMl/ silverlight web resource which may not work post upgrade?

    There are already so many links/ resources available n the approach etc.

    refer the following-

    Hope this helps.

    Just noticed that you are looking for the time it take. I would say it depneds upon the approach you opt for and then how much unsupported stuff you have which you need to remove/ replace.

    To estimate the time, you first need to decide on the approach and a review of you 2011 environment so that you can come up with the estimate.

    For example, if you have a silverlight web resource then you would probably either want to drop t or rereate it with HTMl web resource. And the time to recreate would depend upon the complexity of the component.

    Hope this helps.

    Hi,

    The only way to truly estimate your timescales is to test. I’d strongly recommend setting up migration VMs, one each for CRM 2013 and CRM 2015, and then the final Dev, Test and Production set of CRM 2016/365 machines. You can include SQL Server in the migration VMs if you want. You should then go through at least one trial migration of each of your orgs, noting the time and testing your customisations.

    Even though you say you have very few customisations, going all the way from CRM 2011 to D365 there with be things that can be implemented in a different (and better) manner. There are also some elements of core functionality that work differently, so you many need to make some changes to accommodate these changes.

    Do not commit to a Production migration until you are 100% clear on where you stand and what needs to be changed/updated during the migration.

    Cheers,

    John
