UpgradeConsiderations

CommonconsiderationsthatshouldbetakenintoaccountwhenupgradingGSAconnectorsinclude:

Changestotheconnector

● Someconnectorupgradesincludemajorchangestoconnectordesign,andmayimpactthe

configurationoftheoverallGSAenvironment.Forexample,theGSAConnectorforLotusNotes3.0

introducedearlybindingandifused,requiresthecorrectsecuritymechanismstobeconfiguredfor

authenticationinorderforsecuresearchtofunctioncorrectly.Thesechangesshouldbedetermined

throughanalysisofthenewconnectorfeaturesandanimpactanalysiswithintheexistingGSA

environment.

DependenciesontheGSA

● GSAconnectorsdependonfunctionalitywithintheGSAtooperate,andsomenewversionsof

connectorsaretiedtonewfeaturesintroducedwithintheGSA.Forexample,theGSAConnector

forFileSystems3.0reliesonnewfunctionalityintroducedwithinGSA7.0.

Reindexing

● Whenreindexingconnectorcontent,acompleteretraversalofthecontentsystemisrequired,and

mayimpactperformancethroughtheincreasedloadonthecontentsystem.

● ReindexingwithanewconnectorinstancewillalsoincreaseGSAlicensecountusage,ifexisting

documentsarenotremovedfromtheindexpriortoconnectorupgrade.

● Insomespecialcircumstances,reindexingofallcontentmaynotberequiredwhenperforminga

GSAconnectorupgrade.Thiscircumstancevariesforeachconnectorandeachversion,andshould

onlybedeterminedwithexpertanalysisandguidance.

Changestothetargetcontentsystem

● Someconnectorsrequiresoftwaretobeinstalledontothetargetcontentsource(eg.theGSA

ConnectorforSharePoint)andnewversionswilltypicallyincludeupdatestothesecomponents.

● Thismayalsohavelimitationsforrunningtwoversionsofaconnectorsimultaneouslyduringthe

upgradeprocess(eg.theGSAConnectorforSharePointrequiresanappropriateversionofthe

GoogleServicesforSharePointtobeinstalledontheSharePointserver).

Forcomplexconnectorupgradescenarios,aGSAQualifiedDeploymentSpecialistshouldbeconsultedfor

adviceandguidance.
