&nbsp;Hello&nbsp;ThinkGeo,

&nbsp;

Currently,&nbsp;on&nbsp;Production&nbsp;Windows&nbsp;IIS&nbsp;Server,&nbsp;we&nbsp;are&nbsp;running&nbsp;4.5&nbsp;WMS&nbsp;Server,&nbsp;and&nbsp;we&nbsp;are&nbsp;planned&nbsp;to&nbsp;upgrade&nbsp;to&nbsp;WMS&nbsp;5.5&nbsp;version.

My&nbsp;question:&nbsp;Can&nbsp;we&nbsp;run&nbsp;4.5&nbsp;and&nbsp;5.5&nbsp;side&nbsp;by&nbsp;side&nbsp;concurrently???

If&nbsp;so,&nbsp;What&nbsp;would&nbsp;be&nbsp;the&nbsp;steps??Extract&nbsp;5.5&nbsp;set&nbsp;up&nbsp;on&nbsp;the&nbsp;windows&nbsp;machine,&nbsp;continue&nbsp;installing&nbsp;&nbsp;and&nbsp;enter&nbsp;the&nbsp;license&nbsp;key&nbsp;right???after&nbsp;that&nbsp;do&nbsp;we&nbsp;need&nbsp;to&nbsp;restart&nbsp;the&nbsp;windows&nbsp;machine???

&nbsp;

&nbsp;

&nbsp;

Srikanth,&nbsp;  
&nbsp;&nbsp;  
&nbsp;First,&nbsp;uninstall&nbsp;WmsServerEdition&nbsp;4.5,&nbsp;and&nbsp;then&nbsp;install&nbsp;WmsServerEdition&nbsp;5.5&nbsp;with&nbsp;the&nbsp;same&nbsp;license&nbsp;key,&nbsp;it&nbsp;should&nbsp;be&nbsp;working.&nbsp;  
&nbsp;If&nbsp;you&nbsp;have&nbsp;trouble&nbsp;please&nbsp;contact&nbsp;with&nbsp;[support@thinkgeo.com](mailto:support@thinkgeo.com)&nbsp;  
&nbsp;&nbsp;  
&nbsp;Thanks,&nbsp;

&nbsp;James,

&nbsp;

Thanks.Appreicate&nbsp;for&nbsp;your&nbsp;reply.

So,&nbsp;what&nbsp;&nbsp;you&nbsp;are&nbsp;saying&nbsp;is.....&nbsp;its&nbsp;impossible&nbsp;&nbsp;to&nbsp;run&nbsp;both&nbsp;concurrently.&nbsp;We&nbsp;cannot&nbsp;afford&nbsp;to&nbsp;uninstall&nbsp;and&nbsp;install&nbsp;them&nbsp;on&nbsp;production&nbsp;servers,&nbsp;because&nbsp;most&nbsp;of&nbsp;our&nbsp;customers&nbsp;they&nbsp;expect&nbsp;to&nbsp;have&nbsp;no&nbsp;downtime&nbsp;and&nbsp;too&nbsp;risky&nbsp;to&nbsp;do&nbsp;that.

&nbsp;

Another&nbsp;question:

So&nbsp;can&nbsp;we&nbsp;&nbsp;install&nbsp;WMS&nbsp;5.5&nbsp;on&nbsp;a&nbsp;different&nbsp;windows&nbsp;server&nbsp;with&nbsp;the&nbsp;same&nbsp;key&nbsp;what&nbsp;we&nbsp;have???Can&nbsp;we??

Hi&nbsp;Srikanth,&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;see&nbsp;your&nbsp;problem,&nbsp;but&nbsp;one&nbsp;key&nbsp;can&nbsp;only&nbsp;work&nbsp;for&nbsp;one&nbsp;installation&nbsp;at&nbsp;the&nbsp;same&nbsp;time.&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;think&nbsp;you&nbsp;can&nbsp;contact&nbsp;with&nbsp;[support@thinkgeo.com](mailto:support@thinkgeo.com)&nbsp;or&nbsp;call&nbsp;us&nbsp;for&nbsp;discuss&nbsp;a&nbsp;solution&nbsp;about&nbsp;this.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Regards,&nbsp;

Hi&nbsp;Srikanth,&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;In&nbsp;fact&nbsp;you&nbsp;should&nbsp;can&nbsp;use&nbsp;the&nbsp;dlls&nbsp;of&nbsp;new&nbsp;version&nbsp;to&nbsp;replace&nbsp;the&nbsp;orginal&nbsp;ones,&nbsp;but&nbsp;I&nbsp;don’t&nbsp;have&nbsp;an&nbsp;envrionment&nbsp;for&nbsp;test&nbsp;WmsServerEdition&nbsp;here,&nbsp;so&nbsp;I&nbsp;suggest&nbsp;you&nbsp;did&nbsp;some&nbsp;backup&nbsp;and&nbsp;quickly&nbsp;test&nbsp;for&nbsp;that&nbsp;if&nbsp;possible.&nbsp;  
&nbsp;&nbsp;  
&nbsp;This&nbsp;is&nbsp;just&nbsp;a&nbsp;unofficial&nbsp;suggestion.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Regards,&nbsp;  
&nbsp;&nbsp;
