This is a GUIDE only and not a recommendation of how you should upgrade so test it first and don\u2019t blame me if it goes horrible, blame the gerbil \u2013 if in doubt consult an expert (i.e. not me!)<\/p>\n
Using an account that has EA, DA and<\/strong> SA membership (talk about overkill eh\u2026but trust me it wasn\u2019t working without them), you need to run the adprep tools first, ensure the DC you run it on has the Schema<\/em><\/span><\/strong> Master FSMO<\/em><\/strong> role. Follow these steps:<\/p>\n 1. Copy the ADPREP<\/strong> folder from W2K8 R2 DVDSupportAdprep<\/strong> to a local volume e.g. E:adprep<\/strong>.<\/p>\n Usual gotcha \u2013 make sure you run this from an elevated CMD prompt<\/strong>. Otherwise you get an error about how it cannot check your Group Membership<\/p>\n 3. Change directory to where you copied adprep and type in adprep \/forestprep<\/strong><\/p>\n 4. Press C<\/strong> and then hit ENTER<\/strong> if you are happy to proceed then it does stuff like below<\/p>\n And more stuff<\/p>\n And some more before it is\u00a0finished.<\/p>\n 5. Excellent, now run the following command<\/p>\n adprep \/domainprep \/gpprep<\/strong><\/p>\n Et voila, all preparation tasks finished and you\u2019re ready to roll with the update to R2<\/p>\n 6. In the Windows Explorer GUI browse to your WK8 R2 DVD and run setup<\/strong><\/p>\n 7. Click on the annoying UAC prompt to confirm so you can continue then click Install Now<\/strong>, setup starts<\/p>\n Still starts up<\/p>\n 8. Click on Do not get the latest updates<\/strong><\/p>\n Searches for something<\/p>\n 9. Seems to have found whatever it was looking for, select Windows Server Standard 2008 R2 Standard (Full Installation)<\/strong> (or whatever is relevant for your upgrade), yeah I know it says Full<\/strong> but worry not it will be doing an Upgrade! Click Next<\/strong><\/p>\n 10. Sign your life away, Click Next<\/strong><\/p>\n 11. See, promised you as much. Click UPGRADE<\/strong>!<\/p>\n 12. You\u2019ll get the following compatibility warning…<\/p>\n 13. Resolve any issues and then crack on. Otherwise setup will cancel the upgrade for you if any errors are unresolved. Warnings are acceptable!<\/p>\n Then it does stuff, randomly, and also randomly reboots<\/strong> about 3<\/strong> times!<\/p>\n Oh look, registry still exists\u2026<\/p>\n Is this the final step…<\/p>\n Nope, fooled you, anyone who knows WHY it is copying so many files (nearly a quarter of a million) please email me!<\/p>\n And then it REBOOTS again, third time and counting…<\/p>\n …then like something from a Star Wars movie comes the following<\/p>\n First time use? Eh, i\u2019ve been using this server for nearly a year how can this be the first time!!! Anyway it glows randomly for a little while as it \u2018prepares\u2019 for battle. Bit like a ceylon, sorta<\/p>\n There you go, all that effort for that red R2 at the bottom(!)<\/p>\n![\"r2_pic_1\"](\"http:\/\/www.zulfikar.co.uk\/imgblog\/UpgradingtoWindowsServer2008R2_A87F\/r2_pic_1.png\" "\\"r2_pic_1\\"")
