Approach

Thefollowingstepsdescribetheapproachofmigratingasearchappliancebymirroring:

1. ExaminetheGSAversionofthe“target”GSAandcheckreleasenotesofthisversionandofany

laterpatches,forissuesthatmayaffectthedeploymentenvironment.UpgradethetargetGSAto

theappropriatepatchifnecessary.

2. EnsurebothGSAsareonthesamesoftwareversion,havethesamedocumentlicensecountand

areofcompatiblesearchappliancemodels(seemirroringlinkbelow).Inmanycases,the“source”

GSAwillneedtobeupdatedtothesameversionasthetargetGSA.

3. Pausecrawlingonthesourcesearchappliance,aswellasanyfeedsorconnectortraversals.

4. Configuremirroring,withthesourceGSAsetupasamaster,andthetargetGSAsetupasa

replica.

5. Allowthedatasynctocompleteto100%,toensureallcontentandconfigurationsarecopied.

6. Disablemirroringbetweenthesourceapplianceandthetargetappliance.

7. Resumecrawlonthetargetsearchappliance,andreconfigureanyfeedsorconnectorstostart

sendingnewcontenttothenewtargetsearchappliance.

8. [optional]Ifaproductionbackupapplianceisinuse,enablemirroringandsetupthealready

configuredapplianceasthemaster,andthenewproductionbackupasthereplica.Letthereplica

syncto100%.

9. Cutovertonewappliance(s)anddecommissionoldappliance(s).

Formoreinformationonmirroring,includingcompatibleappliancemodelsanddatathatiscopiedandnot

copiedduringmirroring,see“ConfiguringGSAMirroring”.

Migrationconfigurationsonly

ThealternativemethodtoGSAmigrationisthroughexportingtheconfigurationfilesfromonesearch

applianceandimportingitintoanother.

Sinceimportingaconfigurationfiledoesnotcopythesearchindexfromonesearchappliancetoanother,a

fullcrawlisrequiredtopopulatethesearchindex.Furthermore,anyfeedsorconnectorsmustbeconfigured

toresenddocumentstothenewGSAaftertheconfigurationhasbeenimported.

Thismigrationmethodismostappropriatewhen:

● Changesareplannedtodeploymentarchitecture,suchasnewcontentsourcesbeingintegrated

● NewGSAfeaturesaredesiredthatrequirereindexingofcontent

Advantagesofthismigrationmethod:

● Providesabilitytocontrolwhatcontentisindexedonthenewappliance

● MinimalimpacttothedeploymentofexistingproductionGSAs,asthenewGSAscanbe

configuredandtestedindependentlybeforecuttingover
