I need Upgrade pega 7.4 to pega 8.8.
Hi @MohammadArmanK: What sort of guidance you are seeking from community? Is it on the upgrade guide? Is so you can find it here.
Thanks.
@MohammadArmanK in conjunction with @ArulDevan excellent answer you can also look at the Installation and Update Documentation Roadmap and Pega Platform 8.8 Installation and Update Information support documents which give you a good overview of requirements.
