We are prepping for our upgrade to 6.5 and found that our current SP is 5 and not SP6. Unfortunately we found during the install process to 6.5. IWOV support claims the error we received during the install was due to the attempt to upgrade from SP5 directly to 6.5. Should the SP5 to SP6 update be difficult? Our sys admins have done these before with little fanfare and often in short time over an hour or two after hours. Should we expect any issues?
