Gartner have published a research note for their clients who're stuck on Internet Explorer 6, offering guidance around "Solving the IE 6 Dilemma." But none of options included are very palatable -- at least not according to Gartner.
Gartner notes that a number of organizations still are supporting and/or standardizing on IE 6 -- 9 years after its introduction -- because they've built up sizable installed bases of line-of-business apps that're IE 6-dependent (among other reasons). These organizations aren't easily able to move to IE 8 or Windows 7 because of these dependencies, they said.
Gartner estimates that "organizations running IE6 report that up to 40% of homegrown browser apps fail to run properly with IE8."
"Furthermore, many ISV apps, including complex ERP and CRM apps, with lengthy and expensive migration requirements, must be remediated before IE8 can be used," Gartner officials said in the research note. "Through 2014, IE8 compatibility problems will cause at least 20% of organizations to run overtime or overbudget on their Win7 migration projects," Gartner estimated.
Gartner is suggesting its customers request indemnification clauses be added to their contracts. From the list of recommendations in Gartner's research note:
"Request Microsoft to grant specific contractual amendments to allow you to virtualize IE6 as a Win7 compatibility solution without fear of reprisal (but consider that Microsoft could still pursue your app virtualization vendor with legal action). Organizations in need of IE6 compatibility solutions that don't have sufficient licenses to use Terminal Services and want to comply with Microsoft's recommendation to avoid IE6 app virtualization should petition Microsoft for use of Windows 2003 Server software and associated Remote Desktop Services (RDS) client access licenses (CALs) for the sole use of accessing IE6 at no charge through 8 April 2014."
A Microsoft spokesperson said:
"To help customers take advantage of the modern desktop Microsoft makes available a significant number of resources to help organizations with their migrations to Win7 and IE8 including: Webcasts, Prescriptive guidance, Whitepapers, Tools; and Temporary virtualization solutions.
