Here is the basic outline:
SBS 2003 R2 server that is very messed up but working. I know, but it's true. WSUS dead for years, Symantec Backup Exec broken and can't be fixed, support recommends reload of server, Symantec Endpoint protection broken and can't be fixed, same recommendation, Dynamics GP running on SQL server working, Exchange working. No OS CD's or hardware CD's; only the license sticker on the chassis for SBS. OS partition is RAID 1 array, Data partition is RAID 10 array. Both working without errors. The best we can piece together is that an update to either windows or Dynamics over a year ago that broke windows badly. With all the different support people Microsoft, Symantec, Etc. trying different things to resolve the issues it is worse then it was before they tried to fix anything.
I would like to Migrate to SBS 2011 keeping AD and Exchange. Dynamics is going to be upgraded next month anyway so plan to have them backup data and install on new server then restore the data. Backup Exec no longer licensed, same with Endpoint Protection. Backups are currently using Windows backup with 3 jobs running daily to a USB drive (System State, Exchange and Full) logs look good but no way to really test it. Not that I could reload without the CDs anyway.
I can borrow a new server (just for a few weeks) with 2003 R2 license (not SBS), with a large RAID 1 array, I have approval to buy new OS drives, SBS 2011 Standard and some additional RAM for the existing server. So what I need is an inplace upgrade but i have not confidence that it would work with all the problems that this server has. I would really hate to lose AD and Exchange.
Not sure how to proceed, I have a few ideas but they all scare me. Any help is appreciated.
