Sorry slight correction/edit to my earlier post.
I found the original web page that got me really concerned (sorry it was not the SP1 web page but search partner source or customer source for Hotfix rollup 3 (974407) is available for Microsoft Dynamics AX 2009) The below statement is what got me concerned: The rollup package contains both a cumulative kernel update and a cumulative application update. Although there is no dependency between these two updates, we recommend that you install both of the updates together. The rollup will be installed on the SYP layer and the GLP layer. Additionally, this rollup will update the SYS layer and the GLS layer that are installed on the system It clearly says here SYS and GLS will be updated!!! Any ideas why/what? So I think SP1 does not touch SYS or GLS (sorry for scaring anyone) but it would seem the RU3 does (I really don't understand why since XXP layers are supposed to be exactly for the reason of patching so why is there a need to change the original layer) Thanks James From: James Flavell [mailto:djf1...@gmail.com] Sent: 27 October 2009 16:39 To: 'development-axapta@yahoogroups.com' Subject: GLS or RU3 changes SYS or other system layers? Good afternoon Can anyone advise if the GLS or Hotfix RU3 install exe files update the SYS layer? I read on the web site for SP1 (and also I thought for GLS or RU3 but cannot seem to find now) that it updates the SYS but not sure if that is just some incorrect information on the web site..see: https://mbs.microsoft.com/customersource/downloads/servicepacks/dynamicsax20 09sp1 Other key highlights in this service pack release include: . The SP1 installer updates both the SYS and GLS layers of the product. This means, for example, that if you already have GLS-TR installed on your system, SP1 will update this layer during the installation process. I assumed the above meant SYP or GLP was updated but now I am a little unsure because I always thought SYS was off limits to everyone and only a new version made changes but a binary file compare of a SYS aod from the install DVD compared to after GLS and RU3 being applied shows a different file size and content. Can this change in SYS aod be due to a full compile of the AX application during the GLS or RU3 install or something like that? Would appreciate any help on being sure whether SYS aod file is the same even though the compare shows a difference Thanks James [Non-text portions of this message have been removed]
