Planning upgrade Alfresco community 5.0.b to 6.2

jack_chuong

Hi all,

My environment : Alfresco communitu 5.0.b on premise , server Centos 6.4 , installed all in one by "alfresco-community-5.0.b-installer-linux-x64.bin" .
Installation dir : /opt/alfresco-5.0.b
I actually only use Alfresco content management feature at simple level : upload soft files from scanner to ECM , store and search them later when needed.
I have applied some customizations in /opt/alfresco-5.0.b/tomcat/shared/classes/alfresco-global.properties:
- Authenticate with Active Directory
- Connect to our mail servers
- Use DB Mysql (5.1) and java-1.5.0
- URL : ecm.mydomain.com/share/ (port 80 , not 8080)
- dir.contentstore --> /opt/contentstore (separate from /opt/alfresco-5.0.b/alf_data/contentstore)
May be afew more, I don't remember.

I want to upgrade my ECM to 6.2 , these are my planning steps :

Upgrade path : 5.0.b --> 5.2 --> 6.0 --> 6.2

Stage 1
- Stop ECM services
- Backup alfresco database and contentstore
- Install Alfresco 5.2 on differrent path : /opt/alfresco-5.2 , db alfresco-new , new contentstore
- Apply customizations from old ECM to the new one (except dir.contentstore and db settings)
- Start Alfresco 5.2 services and validate features if it work ok

Stage 2 (if Stage 1 done well)
- Stop Alfresco 5.2 services
- Change Alfresco 5.2 alfresco-global.properties dir.contentstore and db settings to old ECM 5.0.b
- Start Alfresco 5.2 services and validate features if it work ok

Please give me some advices , thank you very much.

1.Direct upgrades to acs 6.2 are supported from 5.1.x and later, so your upgrade path can be just 5.0.b --> 5.2 --> 6.2.
2.Solr4 is not recommended in alfresco 6.X,you should use alfresco search servcie instead. So during upgrade to 5.2,you can upgrade to solr6 directly(you don't need to copy solr4 index,because a reindex is required). in this way when upgrade to acs6.2 from acs5.2,you dont' need to upgrade solr any more .About how to upgrade to search servcie please refer to https://docs.alfresco.com/5.2/concepts/solr6-home.html.
3.For JDK and mysql I suggest you upgrade to to version that alfresco recommended.

After 6.x alfresco don't provide a full installer any more ,docker is recommended.
You can try to install it manually
Plese refer to
http://beecon.buzz/2017/assets/files/EF09/EF09-Installing-Alfresco-components-1-by-1.pdf
and
https://docs.alfresco.com/community/concepts/install-community-intro.html

As far as I know there is not any easy way to install T-egines outside docker.
T-egine is developed using spring boot ,if you don't want to install it using docker ,the only option is to install the spring boot jar and imagemagic/openoffice.. manually.
Now you can turn it off by setting following in your alfresco global properties.

local.transform.service.enabled=false

For fixing the cache problem
Increase the cache size parameter. Add/edit cacheMaxSize within the Context XML element of your $CATALINA_BASE/conf/context.xml. The Resources component inside the <Context block

<Resources
    cachingAllowed="true"
    cacheMaxSize="100000"
/>

you also need to config alfresco endpoint int share-config-custom.xml。

Please refer to

Hi @jack_chuong

Here are some threads that might be worth reading to sanity check your process. Upgrade 5 to 6. Upgrade 5 to 6.2 Docker. Another approach.

HTH,

Hi Eddie, thanks for your reply

I have read all your threads , I just want to make sure , do you think my plan is ok ?
Do I have to copy "/opt/alfresco-5.0.b/alf_data/solr4" to the new one 5.2 so it doesn't have to rebuild full index ?
I will try to upgrade this weekend , if it works, I will try to upgrade to 6.0 then 6.2 next week , but do I have to upgrade mysql and java also ? As "Supported Platforms" says Alfresco 6.2 use MySQL 5.7.23 (mysql-connector-java-5.1.40-bin.jar) and OpenJDK 11

Hi kaynezhang, thank you for your upgrade search service link.

I will install Alfresco 5.2 on new server Centos 7 , mysql 5.7 and java 1.8 (to avoid conflick mysql and java version) , apply customizations , upgrade solr6 and migrate mysql db from old Alfresco 5.0.b to the new one (alf_data contentstore acttually just a NFS mount point from NAS device) , will update to you later.
